Abstract

The application discloses an OLED display panel, a display device, and an array substrate and a manufacturing method thereof. The array substrate comprises a first substrate, a pixel drive film layer, a flat layer, a first pixel definition layer, a reflective layer, an anode layer and a second pixel definition layer. The first pixel definition layer is provided with a plurality of pixel grooves. The reflective layer is arranged on the surface of the first pixel definition layer and covers the pixel grooves completely, thereby improving the utilization efficiency of emergent light of a display sub pixel. Besides, a rough surface is formed on one side, far away from the first substrate, of the reflective layer and thus incident ambient light does not pass through the reflective layer to form mirror reflection, so that a glaring phenomenon is avoided and a problem of absorption of emergent light of a display sub pixel because of utilization of a linear polarizing film for avoidance of the glaring phenomenon can be solved. Therefore, the luminous efficiency of the display sub pixel of the OLED display panel using the array substrate is improved; and the anti-flexure performance of the OLED display panel is enhanced.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to an OLED display panel, a display device, an array substrate and a manufacturing method thereof. Background technique [0002] With the continuous development of display technology, the application of display panels is becoming more and more extensive. Organic light emitting diode (Organic Light Emitting Diode, OLED) display panels have become the leading display panel industry due to their advantages such as fast response speed, brilliant colors, thinness and convenience. rising star. In order to improve the light extraction efficiency of the OLED display panel, it is generally necessary to arrange a reflective metal layer on the array substrate, so that the light emitted by the display sub-pixels of the OLED display panel is emitted toward one side. However, the reflective metal layer also reflects ambient light at the same time, resulting in glare and affec...
