Abstract: A display panel and an electronic device are provided. The display panel includes a first substrate and a second substrate disposed opposite to each other, and a sealant between the first substrate and the second substrate. The light-shielding layer is located on a side of the second substrate facing toward the first substrate, and grooves are defined at positions where the sealant is. The grooves penetrate the light-shielding layer to block a path of water vapor entering the display panel through the light-shielding layer, thereby easing a problem of the intrusion path of the water vapor in current liquid crystal display panels.

Abstract: A display device is provided. In the present application, a liquid crystal compensation layer is provided on both first polarizer and second polarizer, and an improvement of compensation value is not realized by stretching the liquid crystal compensation layer but by adjusting the refractive index difference and thickness of the liquid crystal molecules, so the adjustment range is large, the restriction is small, and it can be matched with the high phase difference of the liquid crystal display panel. Therefore, the dark state side-view light leakage of the liquid crystal display panel and the contrast ratio of the liquid crystal display panel are improved, and the image quality is enhanced.
