Abstract: A display panel and a display device are provided. The display panel includes a color-film substrate, an array substrate, a liquid-crystal layer, and a backlight module configured to provide collimated lights. The display panel includes multiple pixel units. The color-film substrate corresponding to each pixel unit has a first transmission region which transmits lights and a first non-transmission region which does not transmit lights. The array substrate corresponding to each pixel unit has a second transmission region which transmits lights and a second non-transmission region which does not transmit lights. An orthographic projection of the first non-transmission region on the array substrate completely covers the second transmission region. When the pixel unit works in a non-transmission mode, the liquid-crystal layer corresponding to the pixel unit is configured to transmit the collimated lights, and the first non-transmission region is configured to prevent the collimated lights from exiting from the color-film substrate.
