Abstract
The present disclosure provides an OLED display device and a method of making the same. The method includes defining a recess in a first substrate; forming an alignment mark outside the recess; forming a second substrate in the recess; forming a thin film transistor layer and a pixel array layer sequentially on the second substrate. In the present disclosure, the first substrate is accurately aligned with mask plates when forming the pixel array layer, and the second substrate is not deformed during the process of vapor deposition, thereby avoiding the problem of color mixed in vapor deposition.
