Abstract

A liquid crystal display panel includes a first substrate, a second substrate and a liquid crystal layer. The first substrate and the second substrate are disposed opposite to each other, and the liquid crystal layer is located between the first substrate and the second substrate. The first substrate includes a first base, a color filter layer and a first planarization layer. The color filter layer is located on a side of the first base proximate to the liquid crystal layer, and the first planarization layer is located on a side of the color filter layer proximate to the liquid crystal layer and covers the color filter layer. A material of the first planarization layer includes a resin mixture containing polyimide.
