Abstract

A LCD is composed of the first substrate, a LC layer, a black matrix a wall in the black matrix area, and the second substrate, all of which are sequentially arranged.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device using a black matrix. 【Background technique】 [0002] Liquid crystal display is a passive display device. In order to achieve the effect of color display, a color filter needs to be provided for it. Its function is to provide color for the liquid crystal display. components to display different color images. [0003] Please refer to FIG. 1 , which is a schematic diagram of a prior art liquid crystal display device. The liquid crystal display device 20 includes a first base layer 24 and a second base layer 27 filled with a liquid crystal layer 25 . The bottom surface of the second base layer 27 is a TFT array 26 . The first base layer 24 and the coloring layer 22 thereon, the black matrix 23 and the ITO (Indium Tin Oxide, indium tin oxide) layer 21 together constitute a color filter (not shown). The black matrix 23 is distributed in rows and columns on the first base layer 24 to form many gr...
