Abstract

A color filter substrate has a transparent base; a first transparent electrode layer; a black matrix having a plurality of black sections spaced from each other on the first transparent electrode layer; a second transparent electrode layer, and a color resistor layer, in sequence. A method for manufacturing the color filter substrate has steps of: forming a first transparent electrode layer on a transparent base; forming a black matrix having a plurality of black sections spaced from each other on the first transparent electrode layer; forming a second transparent electrode layer on the black sections and the first transparent electrode layer; and forming a color resistor layer on the second transparent electrode layer. The interference of the internal electric field is shielded by disposing the black sections between the first transparent electrode layer and the second transparent electrode layer.
