Problems solved by technology
However, the increase of reflectivity will cause the transmittance to decrease, the luminous efficiency to decrease, and the viewing angle to be worsened.
In order to obtain the best color purity and luminous efficiency, strict cathode and anode thicknesses are required, therefore, it will bring serious challenges to the process of forming cathode and anode

Abstract
An embodiment of the present application provides a display panel, including: a substrate, and an organic light-emitting device placed on the substrate; the organic light-emitting device includes a first electrode, an organic layer, and a second electrode sequentially arranged on the substrate a composite reflective layer, the composite reflective layer is arranged on the side of the organic layer away from the first electrode; the composite reflective layer includes an organic reflective material and an inorganic reflective material; the reflectivity of the organic material is ≤10% , the reflectivity of the inorganic reflective material is ≥60%. The present application can reduce the color shift value of the display panel under a large viewing angle, and obtain the best display effect.
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] In the OLED display panel, the reflectivity of the cathode and the anode can be increased to increase the microcavity effect to improve the color purity of the display panel. However, the increase in reflectivity will result in a decrease in transmittance, a decrease in luminous efficiency, and a worsening of the angle of view. In order to obtain the best color purity and luminous efficiency, strict cathode and anode thicknesses are required, therefore, severe challenges will be brought to the process of forming the cathode and anode. 【Content of invention】 [0003] In view of this, an embodiment of the present invention provides a method to solve the above technical problem. [0004] In one aspect, an embodiment of the present invention provides a display panel, a substrate, and an organic light...
