Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] The transistors used in all embodiments of the present invention may be triodes, thin film transistors or field effect transistors or other devices with the same characteristics. In the embodiment of the present invention, in order to distinguish the two poles of the transistor except the control pole, one pole is called the first pole, and the other pole is called the second pole.

[0046] In actual operation, when the transistor is a triode, the contr...

Abstract

The invention provides a display panel and a display device. The display panel includes a film transistor array layer, a first organic insulating layer, a plurality of first electrodes, a second organic insulating layer, an organic light emitting layer and a second electrode, wherein the first electrode, the organic light emitting layer and the second electrode form an organic electroluminescent device, a first interval is formed between first electrodes included in adjacent sub-pixels with the same color, the second organic insulating layer corresponding to the first interval has a first height, a second interval is formed between the first electrodes included in the adjacent sub-pixels with different colors, the second organic insulating layer corresponding to the second interval has a second height, and the second height is greater than the first height. The display panel is advantaged in that manufacturing difficulty can be reduced, printing precision and the printing speed are improved, and film thickness uniformity of the organic light emitting layer is improved.

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] Organic electroluminescence display panel is a new type of flat panel display device, which has many advantages such as active light emission, high brightness, ultra-thin, low power consumption, large viewing angle and wide operating temperature range. However, in the prior art, when the inkjet technology is used to print the organic light-emitting layer included in the organic electroluminescent display panel, the production difficulty is high, the printing accuracy and printing speed are low, and the film thickness of the organic light-emitting layer is uneven. This phenomenon makes it difficult to control and guarantee the brightness uniformity of organic electroluminescent devices. Contents of the invention [0003] The main purpose of the present invention is to provide a display panel and a disp...
