Problems solved by technology

[0015] However, in the conventional inkjet methods described in Patent Documents 1 to 3, since the uncured sealing portion is in contact with the liquid crystal, there is a problem that impurities are mixed into the liquid crystal and the display quality of the liquid crystal is lowered.

Embodiment 1

[0043] First, refer to Figure 4 The structure of the liquid crystal display panel which is the electro-optic device of the present invention will be described. The liquid crystal display panel 100 of this embodiment has a first substrate 1 and a second substrate 4 arranged oppositely, and liquid crystal display elements 106 and 107 are respectively formed on the inner surfaces of the first substrate 1 and the second substrate 4 .

[0044] Specifically, as Figure 4 As shown, a reflective film (aluminum, silver) 101, a color filter (CF) 102, a protective (OVC) layer 103, a transparent electrode 104, and an alignment film 105 are sequentially formed on the first substrate 1 as the first substrate side. Liquid crystal display element 106.

[0045] On the other hand, a transparent electrode 104 and an alignment film 105 are formed on the opposite second substrate 4 . The transparent electrode 104 is formed of a transparent electrode material such as ITO (Indium Tin Oxide), pro...

Embodiment 2

[0079] Below, refer to Figure 8 with Figure 9 Specific examples of electronic equipment to which the liquid crystal display panel of the present invention can be applied will be described.

[0080] First, an example in which the liquid crystal display panel of the present invention is applied to a display portion of a portable personal computer (so-called notebook computer) will be described. Figure 8 It is a perspective view showing the mechanism of this personal computer. Such as Figure 8 As shown, a personal computer 91 has a main body 912 provided with a keyboard 911, and a display 913 to which a liquid crystal display panel of the present invention is applied.

[0081] Next, an example in which the liquid crystal display panel of the present invention is applied to a display portion of a mobile phone will be described.

[0082] Such as Figure 9 As shown, in addition to a plurality of operation buttons 921, a mobile phone 92 also has a receiver port 922, a speake...

Abstract

The device for manufacturing the electrooptical device has a dam forming means 51 to form the dam part 50 which defines a liquid crystal region on a surface of a first substrate 1, a liquid drop ejecting means 52 to eject a specified amount of liquid drops of a liquid crystal 3 inside the dam part 50, a sealing part forming means 53 to form the sealing part 2 which is located on the outer periphery side of the dam part 50 and seals a second substrate 4 opposite to the first substrate 1 and a pressing means 55 to superpose the second substrate 4 on the sealing part 2 formed on the first substrate 1 and to press the second substrate 4 in vacuum atmosphere 54.

Description

technical field [0001] The present invention relates to a manufacturing apparatus of an electro-optical device, and in particular, provides an electro-optical device capable of improving the quality of a liquid crystal display. Background technique [0002] A liquid crystal device is generally formed by attaching an illuminating device such as a backlight and an additional device such as an IC for driving a liquid crystal to a liquid crystal display panel having a structure in which liquid crystal is sealed between a pair of substrates. [0003] In addition, liquid crystal display panels are generally such as Figure 10 As shown, by attaching the first substrate 1 forming the first electrode and the second substrate 4 forming the second electrode 2 to each other through the sealing part 2, the gap formed between the substrates 1, 4 is a so-called cell. The space is formed by enclosing liquid crystal 3 . In addition, reference numeral 5 denotes a sealing portion that seals t...
