Embodiment Construction

[0037] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The light-emitting device layer comprises a pixel definition layer and a plurality of light-emitting devices arranged in an array; the pixel definition layer comprises a plurality of first openings for exposing the light-emitting devices and a pixel definition structure; the first light adjusting layer comprises a plurality of light adjusting structures, and the light adjusting structures are overlapped with the pixel defining structures; a first gap is formed between every two adjacent light adjusting structures, and the first gaps are overlapped with the first openings; the second light adjusting layer at least partially covers the side wall, facing the first opening, of the light adjusting structure, and the refractive index of the second light adjusting layer is larger than that of the first light adjusting layer; the light adjusting structure comprises a first side and a second side which are oppositely arranged, the first side is located on the side, away from the substrate, of the second side, and the first side comprises a protruding structure protruding towards the direction, away from the substrate, of the first light adjusting layer. The display effect of the display panel can be effectively improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display panel and a display device. Background technique [0002] With the continuous development of display technology, the display panel manufacturing technology is becoming more and more mature. Existing display panels mainly include Organic Light Emitting Diode (OLED), Liquid Crystal Display (LCD), and plasma display panels. (Plasma Display Panel, PDP) and so on. An organic light emitting display device, which is a self-luminous display device, does not require a separate light source. Accordingly, the organic light emitting display device is capable of operating at low voltage, is lightweight and thin, and provides high-quality characteristics such as a wide viewing angle, high contrast ratio, and quick response. Therefore, an organic light emitting display device as a next generation display device has attracted attention. Organic Light-Emitting Diode (OLED...
