摘要: Embodiments of the present disclosure provide a display panel and a display device. The display panel of the present disclosure comprises matrix-arranged pixel units and a grating provided at a light-exiting surface side of the display panel. The grating comprises light blocking zones and light transmission zones provided alternately in a row, and the light blocking zones and light transmission zones are provided alternately in the order of light blocking zone and light transmission zone in one of two adjacent rows and in the order of light transmission zone and light blocking zone in the other of the two adjacent rows, wherein each of at least one light blocking zone blocks completely a pixel unit. The display panel of the disclosure can solve the problem of the moire phenomenon which is caused by the overlap of directions of the light blocking zones of the grating and the black matrix of the existing display panel. In addition, the display effect of the display panel of the disclosure is better.
