Problems solved by technology
[0005] The display panel and the display device provided by the present invention solve the problem that the existing display panel and the display device have different brightness and chromaticity variation rules under different viewing angles due to the light rays of different colors emitted by the organic light-emitting layer, so that the display panel bends at a large viewing angle. The technical problem that the display screen of the folded part is prone to large color shift

Embodiment Construction
[0032] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.
[0033] The present invention is aimed at the display panel and display device in the prior art. Since the light of different colors emitted by the organic light-emitting layer has different changes in brightness and chromaticity under different viewing angles, the display screen of the bending part of the display panel is easy to appear under a large viewing angle. Lar...

Abstract
The invention provides a display panel and a display device. The display panel comprises a flat panel display area and a curved surface display area located at at least one side of the flat panel display area, the display panel comprises an array substrate, a pixel definition layer, an organic light-emitting layer, a cathode layer, a packaging layer and an absorption layer, and the absorption layer is located at the side, away from the array substrate, of the pixel definition layer. The absorption layer is arranged to correspond to at least part of the pixel definition layer located in the curved surface display area and is used for selectively absorbing light of at least one color emitted by the organic light-emitting layer located in the curved surface display area, so that the brightness ratio of multiple colors emitted by the organic light-emitting layer under a large viewing angle is manually adjusted, and the risk of color cast of a white picture under a large visual angle is weakened; and meanwhile, the absorption layer has no absorption interference effect on the forward emergent light of the organic light-emitting layer at the vertical view angle, so that the color cast influence on a picture under the vertical view angle is avoided, and the display effect of the display panel is improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display is a self-illuminating display device, because it can use the characteristics of organic light-emitting materials that can emit light under the condition of external voltage, without the need for additional backlight, Therefore, it has the characteristics of light weight and thinness. In addition, because organic materials are flexible and easy to bend, they are suitable for the development of flexible and foldable displays. Therefore, the proportion of OLED displays in the display field is increasing. [0003] At present, taking advantage of the flexible and easy-bending characteristics of OLED displays, many manufacturers have launched many products such as "curved screens", "surround screens" and "waterfall screens" to further i...
