Abstract
A color filter substrate for an in-cell touch panel, comprising: a base substrate (20); a black matrix (16) disposed on the base substrate (20) and comprising a light transmissive region and a light shielding region; a color filter (17) disposed in the light transmissive region of the black matrix (16); a set of first electrode wires (21) and a set of second electrode wires (22) disposed over the black matrix (16) and the color filter (17) and crossing each other, the first electrode wires (21) comprises a plurality of first electrodes (24) connected in series by a bridge line (23) and the second electrode wires (23) comprises a plurality of second electrodes (26) connected in series by a connection line (25), the bridge line (23) and the connection line (25) crossing each other at a cross region corresponding to the light shielding region of the black matrix (16); and a spacer (19) disposed between the bridge line (23) and the connection line (25) to insulate the bridge line (23) from the connection line (25). With such a structure, the manufacturing process for the color filter substrate in an in-cell touch panel is simplified, and the number of the masks to be used is reduced, and the manufacturing cost is lowered down.
