The present invention provides a color filter substrate and a liquid crystal display panel. Both comprises a color filter layer () 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 () and a second transparent electrode () 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 () and the second transparent electrode () 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.

Color filter substrate and liquid crystal display panel

The present invention provides a color filter and a liquid crystal display. The color filter comprises a substrate, and a color resist layer and a black matrix positioned on the substrate, and the color resist layer comprises a plurality of pixel areas aligned in array, and the plurality of pixel areas are separated by the black matrix, and the pixel area comprises a sub pixel main area and a sub pixel sub area, and two sides of the sub pixel sub area are respectively provided with a first transparent electrode and a second transparent electrode electrically coupled thereto; the sub pixel sub area is made by electrochromic material, and by adjusting voltage signals applied to the two sides of the sub pixel sub area with the first transparent electrode and the second transparent electrode, color variation of the sub pixel sub area is controlled to achieve switch of the color filter between high color saturation and high brightness display modes. The liquid crystal panel of the present invention is provided with the color filter capable of achieving switch of the color filter between high color saturation and high brightness display modes to satisfy the display requirement of high color saturation and high brightness at the same time.
