ELECTROLUMINESCENT DEVICE AND ITS MANUFACTURE METHOD

摘要

An electroluminescent device and its manufacture method are disclosed. The electroluminescent device comprises a color film substrate (20) comprising a substrate (21) and a color filter layer, a boss layer (27), a first electrode (24), an organic electroluminescence layer (25) and a second electrode (26) disposed on the substrate (21); said color filter layer comprises a black matrix (221) and color blocks (222) separated by the black matrix (221); said boss layer (27) is disposed between said color filter layer and said first electrode (24), and the boss layer located above the color blocks (222) protrudes towards the side away from the substrate (21) to form a boss (271); said first electrode (24), said organic electroluminescence layer (25) and said second electrode (26) are disposed on the boss layer (27) orderly, and the second electrode (26) is located above said boss (271). In this electroluminescent device, the reliability of the electrical connection between the thin film transistors and the second electrode can be assured, and the etching difficulty during the manufacture process can be reduced, thereby improving the production efficiency.
