Abstract

Disclosed are a color filter substrate and the manufacturing method thereof. The color filter substrate comprises: a substrate ( 1 ); a black matrix ( 3 ) and a color pixel layer ( 4, 5, 6 ) formed on the substrate ( 1 ); and a transparent thermally conductive layer ( 2 ) disposed between the substrate ( 1 ) and the black matrix ( 3 ) and between the substrate ( 1 ) and the color pixel layer ( 4, 5, 6 ).

First claim

The invention claimed is:

1. A manufacturing method of a color filter substrate comprising:
Step 1, forming a transparent thermally conductive layer on a substrate by coating a transparent thermally conductive material on the substrate and baking and curing it at a temperature of 80-100° C.;
Step 2, forming a black matrix pattern on the transparent thermally conductive layer;
Step 3, forming a color pixel resin layer on the transparent thermally conductive layer,
wherein a thermally conductive material of the transparent thermally conductive layer is formed by a high molecular polymer containing thermally conductive particles, the high molecular polymer is constituted by one or more selected from a group consisting of silica gel, phenolic resin and polyimide, the transparent thermally conductive layer has a thickness ranging from 1 to 5 μm.

2. The manufacturing method of the color filter substrate according to claim 1 , further comprising successively forming a protection layer, an electrically conductive layer and a spacer on the substrate after the step 3.
