Problems solved by technology

[0006] However, in this liquid crystal display device in the past, especially because the semiconductor integrated circuit device 107 is mounted on the right protruding portion 101a of the active substrate 101, the width Wr of the non-display area on the right side of the display area 103 is larger than that of the non-display area on the left side. The width of the display area is W1, and the basic shape in the left and right direction becomes asymmetrical
Therefore, in the case of a mobile phone having such a liquid crystal display device, such as Figure 12 As shown, the position of the display area 103 is shifted to the left side of the main body 11 of the mobile phone, resulting in a poor design effect
Moreover, the size of the left-right direction of the active substrate 101 is relatively large, further making the size of the mobile phone main body 100 relatively large, and the portability is not good.

no. 2 Embodiment

[0065] In the first embodiment above, if figure 1 As shown, the case where the lead wire 7 is arranged only on the right side portion of the active substrate 1 is described, but it is not limited to this. For example it can also be like Image 6As shown in the second embodiment of the present invention. That is to say, in this embodiment, the semiconductor integrated circuit device 11 for data line driving is installed in the center on the lower side protrusion 1a of the active substrate 1, and the semiconductor integrated circuit device 11 for scanning line driving is installed on the left and right sides thereof. Devices 8A and 8B. And, the right end portion of about 1 / 2 of the upper side in the scanning signal line 5 is connected to the output side connection terminal 9A of the semiconductor integrated circuit device 8A for driving the scanning line through the lead line 7b1 arranged on the right side thereof, This semiconductor integrated circuit device 8A is mounted o...

no. 3 Embodiment

[0074] In the above-mentioned second embodiment, the semiconductor integrated circuit device 11 for data line driving is described in the central part on the lower side protrusion 1a of the active substrate 1, and the semiconductor integrated circuit device 8A for scanning line driving is described. The case where 8B is installed on its left and right positions. However, the present invention is not limited thereto. For example, if a semiconductor integrated circuit employs a driver circuit capable of driving both scanning signal lines and data signal lines, then only one semiconductor integrated circuit device is mounted on the active substrate 1 . Figure 8 The illustrated third embodiment of the invention represents such an embodiment. On the lower protruding portion 1a of the active substrate 1, a semiconductor integrated circuit device 31 for data line driving and scanning line driving is mounted. exist Figure 8 Among them, 41 is a flexible printed circuit board bonded...

no. 4 Embodiment

[0076] In the above-mentioned second embodiment, the case where only the lower edge portion of the active substrate 1 protrudes from the counter substrate 2 has been described, but the present invention is not limited to this. For example, it is also possible to Figure 9 As shown in the fourth embodiment of the present invention. In this embodiment, the lower portion and the upper portion of the active substrate 1 are protruded from the opposite substrate 2, and the semiconductor integrated circuit device 33 for driving the data lines is mounted on the central portion of the lower protruding portion 1a. A semiconductor integrated circuit device 34 is mounted to the central portion of the upper side protrusion 1b.

[0077] In this case, about 1 / 2 part of the upper side in the scanning signal line 5, its right end portion is connected to the output side connection terminal (not shown in the figure) of the semiconductor integrated circuit device 34 through the lead wire 27a tha...

Abstract

Right end portions of upper half lines in the scanning signal lines are connected to a semiconductor integrated circuit device via leading lines provided on a right side thereof, and left end portions of lower half lines in the scanning signal lines are connected to a semiconductor integrated circuit device via leading lines provided on a left side thereof. Therefore, the size of a liquid crystal display device in a widthwise direction thereof can be reduced. Also, since crossing points of the leading lines connected to the scanning signal lines are arranged outside the right side edge portion and a left side edge portion of a light shielding film, such a drawback can be prevented from occurring that ionic impurities eluted from the sealing member due a potential difference between the leading lines and the light shielding film corrode the leading lines.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more specifically relates to a liquid crystal display device suitable for mobile phones and mobile electronic devices, etc., capable of reducing the width of a non-display area. Background technique [0002] Figure 11 It is a plan view showing an example of a conventional active matrix liquid crystal display device. The structure of this liquid crystal display device is that the active substrate 101 and the opposite substrate 102 positioned above the active substrate 101 are glued together by a substantially square frame-shaped sealing member (not shown in the figure). Liquid crystal (not shown) is sealed between the two substrates 101 and 102 inside the component. In this case, the right and lower sides of the active substrate 101 protrude from the counter substrate 102 . Hereinafter, these protrusions are respectively referred to as a right protrusion 101a and a lower protrusion...
