Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises an array substrate, a plurality of reflecting electrodes, a plurality of isolation units, an anode layer and a light-emitting function layer. The plurality of reflecting electrodes are positioned on the array substrate and are distributed in an array manner; one isolation unit is arranged between any two adjacent reflecting electrodes; the anode layer comprises a first anode located on each reflecting electrode and a second anode located on the side, away from the array substrate, of each isolation unit, and each first anode and the adjacent second anode are spaced through the corresponding isolation unit; and the light-emitting function layer is located on the first anodes. According tothe invention, two adjacent first anodes can be naturally disconnected through the isolation unit, and the cavity length of the device can be adjusted through the thickness of the first anodes.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Top-emitting OLED (Organic Light Emitting Diode, Organic Light Emitting Diode, Organic Light Emitting Diode, Organic Light Emitting Diode) device has always been a difficult problem in the research and development of OLED devices. One of the main factors affecting the luminous efficiency of the OLED device and the accurate control of the luminous wavelength is: the control of the cavity length of the OLED device (the cavity length generally refers to the direct distance from the reflective electrode at the bottom of the anode to the cathode). Due to the influence of the microcavity effect, the luminous efficiency of each sub-pixel (sub-pixel) and the position of the pop-up are not optimized, especially the position accuracy of the light-emitting pop-up is greatly affected, resulting in a ...
