Abstract

The invention provides an OLED display device and a manufacturing method thereof. The OLED display device comprises: a substrate (100); a plurality of first electrodes (200) spaced apart from each other and arranged in an array on the substrate (100); A pixel barrier layer (300) between the two first electrodes (200); each pixel barrier layer (300) has a groove (310) in the middle, and the groove (310) runs through the pixel barrier layer (300) the OLED organic material layer (400) disposed on the first electrode (200) and the pixel barrier layer (300); the OLED organic material layer (400) is disconnected at the groove (310); and The second electrode (500) arranged on the OLED organic material layer (400); the second electrode (500) is also disconnected at the groove (310). The OLED display device can suppress the leaked emitted light caused by leakage current, reduce short-circuit defects, improve the reliability of the OLED display device, and improve the display quality of the OLED display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display device and a manufacturing method thereof. Background technique [0002] In recent years, flat panel displays such as Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) displays have gradually replaced CRT displays and become mainstream products in the display market. Among them, OLED displays have many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, flexible display and large-area full-color display, etc. It is recognized by the industry as the display with the most development potential. [0003] OLED display devices generally include: a substrate, an anode disposed on the substrate, a hole injection layer disposed on the anode, a hole transport layer disposed on the hole injection layer, a light...
