Problems solved by technology

Under the current process capability, it is impossible to be completely devoid of deviation, and sometimes the deviation can reach ±5μm, so that there will be a great difference between the aperture ratio of the actually produced LCD panel and the design value. The opening ratio difference between them will also be relatively large, which will affect the quality

Embodiment Construction

[0029] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0030] see Figure 3 to Figure 5 , the present invention provides a liquid crystal display device, comprising a liquid crystal panel 1 and a backlight module 2 arranged under the liquid crystal panel 1 .

[0031] Such as image 3 As shown, the liquid crystal panel 1 includes a first substrate 11, a second substrate 12 opposite to the first substrate 11, a liquid crystal layer 13 between the first substrate 11 and the second substrate 12, and an adhesive A sealant 14 that connects the first substrate 11 and the second substrate 12 .

[0032] Such as Figure 4 As shown, the second substrate 12 includes a base substrate 21, a light-shielding metal layer 22 disposed on the base substrate 21, a first insulating layer 23 disposed on the base subs...

Abstract

The invention discloses a liquid crystal display apparatus. A color-resistance layer, a photo-resistance spacer and a TFT layer are all arranged on a second base plate of a liquid crystal panel, so offset amount between layers of the second base plate can be reduced and high para-position precision can be achieved; a backlight module set is arranged on one side close to a first base plate of the liquid crystal panel and the second base plate is in a top-grid structure, so when a light source of the backlight module set enters from the first base plate side to the liquid crystal panel, a grid can cover a channel region of a polycrystalline silicon layer and great improving effect can be achieved for leak current of the second base plate; besides, a light-shielding metal layer of the side bottom layer of the second base plate is made of black metal; when external light enters from the second base plate side, with the light-shielding layer on the bottommost layer, a problem of contrast ratio decrease of the panel due to metal reflection by the incidence of light from the second base plate can be solved; and the liquid crystal display apparatus is simply structured and black matrix manufacturing can be avoided compared with the prior art.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] Liquid crystal display (LiquidCrystalDisplay, LCD) has many advantages such as thin body, power saving, no radiation, and has been widely used, such as: mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc. . [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. The structure of a traditional liquid crystal panel is composed of a color filter substrate (ColorFilterSubstrate), a thin film transistor array substrate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate), and a liquid crystal layer (LiquidCrystalLayer) arranged between the two substrates. A driving voltage i...
