Abstract

The present invention provides a liquid crystal display (LCD) panel and a liquid crystal display apparatus. The LCD panel comprises a color filter sheet. A second substrate of the LCD panel comprises a plurality of pixel units. Each of the color filters of the LCD panel corresponds to one of the pixel regions of the pixel units. A liquid crystal layer is disposed between the first substrate and the second substrate. The color filter sheet includes color regions corresponding to the color filters, respectively, wherein the color regions and the corresponding color filters have the same color.
