Abstract

The invention provides a color filter. The color filter comprises a substrate, a first transparent conductive layer, a second transparent conductive layer, an alignment layer and sealing frame glue, wherein the first transparent conductive layer is arranged at the edge of the periphery of the substrate and has a 'double-stacked-square'-shaped structure; the second transparent conductive layer covers the first transparent conductive layer and extends to a position above the substrate; the second transparent conductive layer comprises a flat portion arranged on the substrate and a step portion which is arranged above the first transparent conductive layer and is connected with the flat portion; the alignment layer is arranged on the flat portion; and the sealing frame glue is arranged on thestep portion. The 'double-stacked-square'-shaped first transparent conductive layer is additionally arranged at the edge of the periphery of the substrate, then the edge of the second transparent conductive layer is heightened, the alignment layer is effectively stopped from flowing to the edge of the periphery, the sealing frame glue is prevented from pressing the alignment layer, steam is stopped from entering the color filter, and finally, the stability of the color filter is improved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a color filter, a preparation method and a display device. Background technique [0002] BPS (Black Photo Spacer, black spacer) technology combines BM (Black Matrix, black matrix) and PS (Photo Spacer, spacer) two technologies into one, which reduces the steps of the process and reduces the cost. The efficiency is improved, and it is now widely used in the preparation of a CF filter (Color Filter, color filter). However, since there is no PS barrier in the BPS technology, it is impossible to prevent the alignment liquid (Polyimide, polyimide) from flowing to the surrounding edges of the transparent conductive layer. Therefore, when coating the sealant, the sealant sealant will press on the alignment layer. Since the alignment layer is organic, it is easy to absorb water, which will cause water vapor to enter the optical filter, making the circuit easy to be corrode...
