Patent ID: 8531643

Claim:
A color filter substrate, characterized in that: comprising a substrate, a plurality of color filtering units, a display-area black matrix, an edge black matrix, wherein the color filtering units, the display-area black matrix, the edge black matrix and a transparent conductive layer are formed on the substrate in turn; the display-area black matrix is connected to the edge black matrix along an extension direction; the edge black matrix surrounds a display area of a liquid crystal panel and then forms an edge light-shielding area corresponding to a periphery of the display area, wherein the color filter substrate further has a plurality of photo spacers formed on the transparent conductive layer, arranged on the periphery of the display area, and are extended into the edge light-shielding area formed by the edge black matrix along the extension direction of the display-area black matrix relative to the edge black matrix; each of the photo spacers has a length disposed in the display area that is smaller than or equal to 30 mm, and has another length disposed in the edge light-shielding area that is smaller than or equal to 20 mm; and each of the photo spacers is separated from the adjacent photo spacer at a distance to form a slit therebetween, liquid crystal material in the display area flows through the slit to the edge light-shielding area by capillarity.
