Abstract
The present invention provides a liquid crystal panel and a color filter substrate thereof. The color filter substrate includes a substrate, a plurality of color filtering units, a display-area black matrix, an edge black matrix, and 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 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, and 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; 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, so as to prevent liquid bubbles from being formed at the edges of the display area and to enhance production yield of the liquid crystal panel.
