Problems solved by technology
[0003] The object of the present invention is that due to the impact of the gap, transverse electric field, etc. in the middle of the D line and the shading line of the existing TN type liquid crystal display, the orientation of the liquid crystal is chaotic, causing oblique light leakage, although there is a BM layer on the CF to cover this Part of the light leakage, but in the actual manufacturing process, the problem of edge light leakage will be caused by alignment and other problems. A method to improve the light leakage at the edge of the LCD pixel is invented to fundamentally block the light leakage

Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0014] Such as image 3 A method for improving light leakage at the edge of a pixel of a liquid crystal display is shown, adding a light-absorbing layer 9 formed of a light-absorbing material between the data line 5 and the shading line 8, fundamentally preventing light from being transmitted between the data line 5 and the shading line 8 come out as image 3 shown. The size of the light-absorbing layer 9 is required to completely cover the gap between the data line 5 and the shading line 8, with a width of 0.5-3um and a thickness of 0.2-1um. During specific implementation, the light-absorbing layer 9 coated between the data line 5 and the shading line 8 without mutual contamination with the liquid crystal material can be between the data line 5 and the shading line 8, or between the G line and the shading line 8 between. The light-absorbing layer 9...

Abstract
The invention relates to a method for improving pixel edge light leakage of a liquid crystal displayer. The method is characterized in that a light absorbing layer made of a light absorbing material is additionally arranged between a data line and a shading line, and light is prevented from being transmitted from the portion between the data line and the shading line fundamentally. The problem of edge light leakage caused by disordered liquid crystal orientation between the data line and the shading light is solved, and the contrast ratio is increased.
Description
technical field [0001] The invention relates to a liquid crystal display, in particular to a method for preventing light leakage at the edge of the display, in particular to a method for improving light leakage at the edge of pixels of the liquid crystal display. Background technique [0002] At present, TN-type liquid crystal display is a relatively common liquid crystal display mode, which is generally a normally white type, and it will be in a black state after the maximum gray scale voltage is applied. Between the data line and the shielding line of the TFT, after voltage is applied, the orientation of the liquid crystal molecules is chaotic, so a BM is added on the side of the color filter to prevent oblique light leakage on the TFT side. But on the side of the color filter, the alignment accuracy must be considered. When there is a deviation in the alignment, we can observe light leakage from the edge of the LCD pixel from some angles. Between the data line and the sh...
