Embodiment Construction

[0044] FIG. 2 is a schematic cross-sectional view of a light-shielding structure according to an embodiment of the present invention. 2A-2C are schematic top views of the flow channels of the light-shielding structure in FIG. 2 . Please refer to FIG. 2 and FIGS. 2A-2C at the same time. The light-shielding structure 200 is suitable for disposing on the substrate 300. The substrate 300 has a display area 300a and a non-display area 300b. The black matrix layer 210 is disposed on the substrate 300 and defines a plurality of sub-pixel regions 210a in the display region 300a, and the black matrix layer 210 covers the non-display region 300b adjacent to the edge of the display region 300a. The light shielding layer 220 is disposed on the black matrix layer 210 of the non-display region 300 b adjacent to the edge of the display region 300 a , and the light shielding layer 220 has at least one channel 222 .

[0045] Please refer to FIG. 2 again. In one embodiment, the material of the...

Abstract

The invention disclseos a light screening structure, arranged on a substrate, where the substrate has display region and non-display region, and the light screening structure comprises black matrix layer and light screening layer, the black matrix layer is arranged on the substrate and defines multiple pixel regions in the display region and covers the non-display region adjacent to the edges of the display region; the light screening layer is arranged on the black matrix layer adjacent to the non-display region on the edges of the display region, the light screening layer has at least a flow channel; and the light screening structure can improve the phenomenon of light leakage on the edges of the display region of the LCD panel. In the LCD making course, the invention can avoid liquid crystal pollution. Besides, the invention advances a color filter substrate with the light screening structure, an active component array structure and the LCD panel thereof.

Description

technical field [0001] The present invention relates to a light shading structure, a filter substrate, an array substrate and a display panel, and particularly relates to a light shading structure for improving light leakage and having a liquid crystal flow guide function. , and a color filter substrate, an active element array substrate and a liquid crystal panel having the light-shielding structure. Background technique [0002] With the development of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (FlatPanel Display) with thin and light characteristics has also matured. These flat-panel displays are, for example, liquid crystal displays (LCDs), organic electroluminescent displays (OLEDs) or plasma displays (PDPs). Displays have gradually become the mainstream of the market. [0003] Generally speaking, a liquid crystal display is composed of a liquid crystal panel and a backlight module, wherein the liquid crystal panel is c...
