Abstract

The invention discloses a display panel and a manufacturing method thereof. The manufacturing method comprises the steps of: providing a substrate; forming an active switch on the substrate; forming a light emitting layer on the active switch, and electrically connecting the light emitting layer to the active switch; forming a flat layer between the active switch and the light emitting layer, wherein the flat layer is provided with a through hole; and, filling a colourful photoresist layer in the through hole of the flat layer, wherein the colourful photoresist layer is aligned to the light emitting layer. Thereby, the display effect of a self-light-emitting display panel can be well ensured.

Description

Technical field

[0001] The present invention relates to the field of display technology, and more specifically, to an organic light emitting diode display panel and a manufacturing method thereof. Background technique

[0002] Active-matrix organic light emitting diode (AMOLED) display has the characteristics of high contrast, wide color gamut, and fast response speed. Because AMOLED is self-luminous and does not need a backlight, it can be made lighter, thinner and even more flexible than AMLCD. The AMOLED display screen is mainly controlled by a specific TFT to adjust the switch and brightness of the OLED device, and the screen is displayed after adjusting the ratio of the three primary colors. Among them, the control TFT often uses a metal oxide semiconductor, which not only has a higher on-state current and a lower off-state current, but also has the characteristics of higher uniformity and stability.

[0003] After the anode manufacturing process, the pixel definition layer ...
