Problems solved by technology

However, when the light-shielding film is set to white or silver, contrary to the case where the light-shielding film is set to black, the periphery of the display area of ​​the liquid crystal display device will be brighter than the center, and bright lines will appear to blur the display.
The cause of this problem is considered to be that if the width of the frame portion of the liquid crystal display device is narrow, the distance between the display area of ​​the liquid crystal display device and the light-shielding film becomes closer, especially when the display screen is viewed obliquely. Impact is bigger than ever

Embodiment approach 1

[0038] Use below Figure 1 to Figure 4 The liquid crystal display device of Embodiment 1 will be described.

[0039] In each of the following figures, in order to make each component easier to see, it may be shown with a different scale depending on the component.

[0040] The liquid crystal display device 1 of the present embodiment is, for example, figure 1 As shown, a liquid crystal panel 2 , a backlight 3 , a frame 4 , and a tape 5 for bonding are provided. The backlight 3 is configured in figure 1 The lower side of the middle liquid crystal panel 2. The backlight 3 emits light for illuminating the liquid crystal panel 2 . The backlight 3 of the present embodiment corresponds to the lighting device in the claims. The frame 4 supports the liquid crystal panel 2 and the backlight 3 . The joining tape 5 joins the liquid crystal panel 2 and the frame 4 .

[0041] In the liquid crystal display device 1 , light emitted from the backlight 3 is modulated for each pixel of t...

Embodiment approach 2

[0076] Use below Figure 5 Embodiment 2 will be described.

[0077] The basic structure of the liquid crystal display device of the present embodiment is the same as that of the first embodiment. The liquid crystal display device of this embodiment differs from Embodiment 1 only in the structure of the bonding tape. Therefore, in the present embodiment, the joining tape will be described.

[0078] exist Figure 5 , for the same as that of Embodiment 1 image 3 Common structural elements are given the same reference numerals.

[0079] Such as Figure 5 As shown, in the joining tape 54 of this embodiment, the colorless and transparent adhesive layer 51 is provided on the first surface 49 a of the base material 49 . The color of the first surface 54 a of the joining tape 54 reflects the color of the base material 49 . The color of the first surface 54 a of the joining tape 54 is black in which the lightness of an achromatic color is 1 or more and 5 or less in the Munsell c...

Embodiment approach 3

[0085] Use below Figure 6 Embodiment 3 will be described.

[0086] The basic structure of the liquid crystal display device of the present embodiment is the same as that of the first embodiment. The liquid crystal display device of this embodiment differs from Embodiment 1 only in the structure of the bonding tape. Therefore, in the present embodiment, the joining tape will be described.

[0087] exist Figure 6 , for the same as that of Embodiment 1 image 3 Common structural elements are given the same reference numerals.

[0088] Such as Figure 6 As shown, in the joining tape 57 of this embodiment, the colorless and transparent adhesive layer 51 is provided on the first surface 49 a of the base material 49 . The color of the first surface 57 a of the joining tape 57 reflects the color of the base material 49 . The color of the first surface 57 a of the joining tape 57 is black in which the lightness of an achromatic color is 1 or more and 5 or less in the Munsell c...

Abstract

The invention provides a liquid crystal display device which is provided with a belt for combining. The belt for combining is used for combining a liquid crystal panel and a frame, a first face of the belt for combining is connected with the liquid crystal panel, a first part of a second face of the belt for combining is connected with a first face, a second part of the second face extends out of the first face of the frame, the side face of the liquid crystal panel is exposed to the outer space of the frame, and the luminous reflectance of at least the second part of the second face of the belt for combining is higher than that of the first face of the belt for combining.

Description

technical field [0001] The present invention relates to a liquid crystal display device. Background technique [0002] A transmissive liquid crystal display device includes a liquid crystal panel and a backlight for irradiating light to the liquid crystal panel. In such a liquid crystal display device, when the light irradiated from the backlight leaks into the non-display area around the liquid crystal panel, problems such as deterioration of display quality and light utilization efficiency occur. [0003] Patent Document 1 below discloses a liquid crystal display device provided with a light-shielding film for blocking light leakage as described above. The liquid crystal display device disclosed in Patent Document 1 includes a liquid crystal display panel, a backlight unit, and a mold frame having protrusions. The liquid crystal display panel is supported on the raised portion of the mold frame. The backlight assembly is disposed under the raised portion of the mold fra...
