Abstract
A liquid crystal display panel includes a first transparent glass layer; a second transparent glass layer overlapping the first transparent glass layer; two or more pixel units disposed on a side of the first transparent glass layer opposite to the second transparent glass layer, each of the pixel units including a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel arranged in accordance with a predetermined rule; a black matrix disposed between the pixel units to isolate two pixel units adjacent to each other; and a fingerprint sensor disposed on the second transparent glass layer, and covered by the black matrix; when the fingerprint sensor is viewed from the top, an area of the fingerprint sensor corresponding to a region of the red sub-pixels is larger than any one of areas of the fingerprint sensors corresponding to respective regions of the green, blue, and white sub-pixels.
