Abstract
An OLED display and manufacture method thereof are provided. The OLED display includes a TFT substrate, the TFT substrate having a plurality of light-blocked pixel isolation layers and a plurality of OLED emissive layers on a surface thereof, and each OLED emissive layer having cathode on a surface thereof. The light-blocked pixel isolation layer includes a wall portion, and the wall portion having a light-blocked portion on a surface thereof. The TFT substrate has a plurality of pixel regions surrounded by the wall portions of the light-blocked pixel isolation layers on the surface thereof. Each pixel region respectively has the OLED emissive layer therein. The OLED display and method avoid light leakage caused by the oblique light of each pixel region emitted into adjacent pixel regions while the OLED emissive layer lighting.
