Abstract

Embodiments of the present disclosure disclose a display panel and a display device. The display panel includes: a base substrate and a plurality of pixels located on the base substrate, and an encapsulation layer located on the plurality of pixels. The display panel includes at least one transparent region and a display region outside the at least one transparent region. The plurality of pixels is located in the display region. The transparent region of the display panel is configured to allow non-polarized radiation passing therethrough without substantially polarized. In a direction parallel with the base substrate, a width of the transparent region is substantially greater than a distance between adjacent two of the pixels on the same side of the transparent region. In a plan view, the transparent region is completely located within at least one of the base substrate and the encapsulation layer.
