Abstract: A display device is provided, including a display screen; a first polarizer arranged on a light-emitting surface of the display screen; a light splitting sheet arranged on a side of the first polarizer away from the display screen, wherein a direction of a light transmission axis of the light splitting sheet is consistent with a direction of a light transmission axis of the first polarizer; a first quarter-wave plate arranged on a side of the light splitting sheet away from the first polarizer; a first lens arranged on a side of the first quarter-wave plate away from the light splitting sheet; and a transflective film arranged on a side of the first lens away from the first quarter-wave plate.

Abstract: A liquid crystal display panel is provided. A micro-lens array, a black matrix layer array, and a detector array are sequentially disposed between a cover plate and an array substrate, and a combination of the micro-lens array and the black matrix layer array filters out more interference light, so that most of light entering the detector array is fingerprint reflected light, which improves an accuracy of fingerprint recognition. A liquid crystal display device having the liquid crystal display panel is also provided.
