Abstract
The present invention provides a color filter substrate and a liquid crystal display panel. Both comprises a color filter layer (11) having a plurality of red filters, green filters, blue filters (R, G, B) and color change filters (C) aligned in matrix, and a first transparent electrode (41) and a second transparent electrode (42) are respectively positioned at two sides of the color change filter (C), and material of the color change filter (C) is electrochromic material. The color change filter (C) is applied with voltage signals via the first transparent electrode (41) and the second transparent electrode (42) to control color change of the color change filter (C) for conveniently achieving high brightness and high color saturation display; as appearing to be transparent, the transmission is high to satisfy the demand of high brightness display; as the color change filter (C) appears to be a specific color which is not red, green, blue, such as cyan, four colors display can be realized to promote the color expression ability to satisfy the demand of high color saturation display.
