COLOUR FILM SUBSTRATE AND PREPARATION METHOD THEREFOR, AND DISPLAY DEVICE

摘要

A colour film substrate and a preparation method therefor, and a display device comprising the colour film substrate, which relate to the technical field of displays. The colour film substrate comprises an underlayment substrate (10), a black matrix (20), a colour filter layer (30) and a transparent conducting layer (40), wherein the transparent conducting layer (40) is formed between the underlayment substrate (10) and the colour filter layer (30). By arranging the transparent conducting layer (40) of the colour film substrate between the underlayment substrate and the colour filter layer, the transparent conducting layer (40) of the colour film substrate is isolated from the transparent conducting layer of the array substrate, and bad phenomena of bright lines or bright spots, etc. caused by abnormal breakover of the transparent conducting layer of the colour film substrate and the transparent conducting layer of the array substrate due to micro-particles deposited on the transparent conducting layer of the colour film substrate or the transparent conducting layer of the array substrate, are effectively avoided.
