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.

Claim (Index 9):
The method according to  claim 5 , wherein\n if the light-blocked pixel isolation layer is composed of light sensitive material, the STEP S 2  of generating the TFT substrate having a plurality of light-blocked pixel isolation layers further comprises: coating a first pixel isolation layer on the surface of the TFT substrate, and exposing and developing the first pixel isolation layer by a halftone mask to form the light-blocked pixel isolation layer; or if the light-blocked pixel isolation layer is composed of light non-sensitive material, the STEP S 2  of generating the TFT substrate having a plurality of light-blocked pixel isolation layers further comprises: generating the TFT substrate having a second pixel isolation layer on a surface thereof, and after then generating the second pixel isolation layer having light-blocked portion on a surface thereof; exposing and developing the light-blocked portion by the halftone mask to form a light-blocked pattern corresponding to the light-blocked pixel isolation layer, wherein the thickness related with a first portion of the light-blocked pattern corresponding to the light-blocked portion is greater than the thickness related with a second portion being exclusive of the first portion of the light-blocked pattern corresponding to the light-blocked portion, the second pixel isolation layer is etched by utilizing the light-blocked pattern to be a block to remove unblock portion of the second pixel isolation layer, after then the light-blocked pattern is performed by an ashing process to remove the second portion being exclusive of the first portion of the light-blocked pattern corresponding to the light-blocked portion, and the second pixel isolation layer is etched by utilizing the light-blocked pattern performed by the ashing process to form the light-blocked pixel isolation layers.
