Abstract

The embodiment of the invention provides a display panel, and the display panel comprises a substrate, pixel definition layers arranged on the substrate, an organic light-emitting device arranged between the pixel definition layers, an encapsulation layer arranged on the pixel definition layers and the organic light-emitting device, and a color film structure layer arranged on the encapsulation layer. The color film structure layer comprises a plurality of color resistance layers, wherein the orthographic projection area of the color resistance layers on the substrate coincides with the orthographic projection area of the organic light-emitting device on the substrate, and the face, away from the organic light-emitting device, of each color resistance layer is a concave face. The inventionfurther discloses a manufacturing method of the display panel and a display device. Due to the fact that the thicknesses of the color resistance layers in the direction perpendicular to the substratebase plate are not equal, the light can be diffused after passing through the color resistance layers, the light entering human eyes under different visual angles is correspondingly compensated, andthe white balance is adjusted; meanwhile, the color gamut improvement under different visual angles is facilitated, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device has the characteristics of self-luminescence, simple structure, ultra-thin, fast response, wide viewing angle, low power consumption and flexible display, so it is widely used in display field. [0003] COE (ColoronEL) technology is to form a color-resistive layer (ie, color film layer) on an organic electroluminescence (EL) device in thin film encapsulation (ThinFilmEncapsulation), that is, the structure of "R / G / B three primary colors + color film", which can be used It is used to replace the traditional polarizer technology, effectively reduce the reflectivity of OLED panels, improve color purity, increase color gamut, reduce panel thickness, and improve panel display brightness. [0004] However...
