Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0028] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel has many advantages such as full solid state, active light emission, fast response speed, high contrast ratio and flexible display, and has wider development space. The current OLED display panel takes advantage of flexibility and bendability, and a bending structure is formed at the edge of the display panel to form a bending area, which helps to realize the narrow frame and full-screen display effect of the OLED display device....

Abstract
The invention discloses a display panel and a display device. The display panel includes a substrate, a light-emitting unit on the substrate, and a light extraction layer located on the side of the light-emitting unit away from the substrate; the substrate includes a planar area and a bending area located on at least one side of the planar area; along the direction of the substrate pointing to the light-emitting unit, light The unit includes a first electrode, a light-emitting functional layer and a second electrode stacked in sequence; the thickness of the light-emitting functional layer corresponding to the planar area is different from the thickness of the light-emitting functional layer corresponding to the bending area; the optical thickness of the light extraction layer corresponding to the planar area The optical thicknesses of the light extraction layers corresponding to the bending regions are different. The technical solution of the present invention can adjust the attenuation speed of light of different colors with the viewing angle, improve the viewing angle deviation in the bending area, reduce the degree of color shift in the bending area and the plane area, and improve the display effect of the display panel. At the same time, it can ensure that the display colors of the flat area and the bending area are the same under a small viewing angle, thereby improving the display effect of the display panel.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] In the display panel, there is a problem of asynchronous observation angles in the flat area and the bending area of the display panel under the field of view, resulting in different degrees of color shift in the display screens in the flat area and the bending area. Contents of the invention [0003] The invention provides a display panel and a display device to improve the color shift in the bending area and reduce the color shift difference between the plane area and the bending area. [0004] In the first aspect, an embodiment of the present invention provides a display panel, which is characterized by comprising a substrate, a light emitting unit located on the substrate, and a light extraction layer located on a side of the light emitting unit away from the substrate; [000...
