Abstract
The present disclosure relates to a color filter substrate, a manufacturing method thereof, and an OLED display device. The color filter substrate comprises a substrate, a black matrix, a plurality of color resists, and a plurality of isolation walls. The present disclosure disposes the plurality of isolation walls on the black matrix and between two adjacent color resists, thereby preventing light crosstalk between the adjacent color resists and preventing color mixing, and therefore improving display effect.
