Claim:
1. A substrate for a liquid crystal display panel, comprising: a base substrate; a color filter layer disposed on the base substrate and configured as a color filter layer of the liquid crystal display panel, the color filter layer including a plurality of color filters including red filters, green filters and blue filters arranged in a matrix; a plurality of black matrix units each located between two adjacent color filters so as to space the two adjacent color filters apart from each other; a plurality of thin film transistors, each thin film transistor being arranged so that its projection area on the base substrate is located within a projection area of a corresponding black matrix unit on the base substrate; and first and second transparent electrodes respectively disposed on left and right sides of the color filter layer such that the first transparent electrode, the color filter layer and the second transparent electrode are disposed in the same layer on the base substrate, and the first transparent electrode and the second transparent electrode are electrically connected with the color filter layer, wherein the color filter layer comprises an electrochromic material layer, which is configured to change its color based on gray scale of an image to be displayed on the liquid crystal display panel.
