Abstract: A display panel and a display device are provided. The display panel comprises sub-pixel electrodes and data line groups. The data line group includes at least two sub-data line groups. The sub-pixel electrode includes at least two sub-pixel electrode sections. By dispersing the data lines in the data line group into each sub-data line group and arranging the plurality of the sub-data line groups on two sides of the sub-pixel electrode sections in each of the columns, the shading area of each of the data line groups can be reduced, thereby improving the problem of dark stripes on the display panel.

Abstract: A display device provided includes a display panel, a first backlight module, a second backlight module, a light sensor, and a viewing angle adjusting component. The first backlight module includes an optical element, and the viewing angle adjusting component is disposed corresponding to a display sensing area. When the optical element is in a fog state, the viewing angle adjusting component reduces an exit angle of backlight. When the optical element is in a transparent state, external light enters the light sensor through the viewing angle adjusting component and the first backlight module, which improves uniformity of backlight viewing angle.
