Liquid crystal display device and manufacture method and optical diaphragm thereof

Abstract

The invention provides an LCD device, a manufacturing method thereof, and an optical film. The LCD device includes optical films, and an LCD panel; an edge(s) of the optical film is provided with a folded edge(s), and the LCD panel is arranged on the folding edges. In the invention, because the folded edges are arranged on the optical film of the LCD device, and the LCD panel is arranged on the folding edges, no interval is reserved between the edges of the LCD panel and the optical films, thereby preventing the LCD device from generating light leakage because the LCD panel is supported by the separated middle frames. In addition, because no interval is reserved between the edges of the LCD panel and the folded edges for support, the whole edges of the LCD panel are continuously supported instead of only supporting the four corners by the separated middle frames, thereby increasing the compression strength of the LCD panel, effectively preventing the black matrix or other structure(s) from moving because of oversize deformation when being stressed, and preventing light leakage and water ripple phenomena.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and more specifically, relates to a liquid crystal display device, a manufacturing method thereof, and an optical film. Background technique [0002] Liquid crystal display devices are becoming more and more popular due to their low power consumption and small size. However, with the development of liquid crystal display technology, some existing problems have also been discovered. [0003] like figure 1 As shown, it is a structure of a liquid crystal display module of an existing liquid crystal display. The structure of the liquid crystal display module is connected by a plastic frame 25, so that the liquid crystal panel 10 and the backlight module 20 are assembled together to realize the normal operation of the liquid crystal display. The liquid crystal panel 10 is at the top, supported by the supporting part 251 on the plastic frame 25, and an optical film is pressed under the plastic fr...

AI Technical Summary

Problems solved by technology

In order to reduce material cost, the applicant once tried to try as figure 2 In the solution shown in , the liquid crystal display module supports the four corner regions of the liquid crystal panel through four separate plastic frames 25 respectively. There is a problem with the liquid crystal module assembled through this structure, that is, because the separate There is a gap between the plastic frames 25, so that the liquid crystal panel bends downward when it encounters pressure, and then the black matrix on the liquid crystal panel moves, so that light leakage occurs and water ripples occur, which seriously affects the LCD. In addition, for the split-type plastic frame 25, the distance between the four split-type plastic frames 25 located on the liquid crystal panel is too large, resulting in too large a gap between the liquid crystal panel and the optical film, resulting in side light leakage , so that the optical taste of the whole module is seriously affected
