Abstract
An OLED display includes a first substrate including a thin film transistor and an organic light emitting element and a second substrate facing the first substrate and having a gully pattern recessed on a surface facing the first substrate. By having the gully pattern on the second substrate, a mechanical strength of the OLED may be improved, and thus, the OLED may minimize the thickness without reducing the mechanical strength.
Claims14
An organic light emitting diode (OLED) display, comprising:
- a first substrate including a plurality of pixels, each pixel including at least one thin film transistor and an organic light emitting element, the organic light emitting element of each pixel including a light emitting region and a non-light emitting region;
- and
- a second substrate facing the first substrate and having a gully pattern recessed on a surface facing the first substrate, the gully pattern including a plurality of grooves arranged on the second substrate, the plurality of grooves being between individual pixels to correspond to non-light emitting regions of the pixels.
