Abstract
The present application provides a pixel defining layer and a manufacturing method thereof, an array substrate, a display panel and a display device, which are used to improve the problem of the large viewing angle of OLED products in the prior art. The pixel defining layer includes at least a first defining layer and a second defining layer; the position of the first defining layer corresponds to the position of the light emitting layer of the first luminescent color, and the position of the second defining layer corresponds to the position of the light emitting layer of the second luminescent color ; The thickness of at least part of the first defining layer is greater than the thickness of the second defining layer. Since the thickness of at least part of the first defining layer is greater than the thickness of the second defining layer, the first defining layer can block the light passage of part of the light emitted by the light emitting layer of the first luminous color, thereby making the luminous brightness of the light emitting layer of the first luminescent color The proportion is reduced to achieve white balance of white light brightness under large viewing angles.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a pixel defining layer and a manufacturing method thereof, an array substrate, a display panel and a display device. Background technique [0002] Active Matrix Organic Light Emitting Diode (AMOLED) is an active light-emitting device that does not require a backlight source. As long as organic light-emitting materials are evaporated on the display backplane, it can be driven by current to obtain stable current and emit light. Its power consumption, contrast ratio and other parameters are superior to liquid crystal display (Liquid Crystal Display, LCD) products. [0003] The inventors of the present application found that due to the material characteristics of organic light-emitting materials and the structural design of OLED devices, current OLED products have the problem of being blue at large viewing angles. Contents of the invention [0004] In view of this, the ...
