Abstract: A display device includes a display panel including a plurality of pixels, an illuminance sensor to measure illuminance, and a display controller which includes a processor a brightness controllers. The processor calculates an external illuminance value with reference to a signal from the illuminance sensor. The brightness controller turns off at least one of the pixels and controls the brightness of the display panel when the calculated external illuminance value is in a first region. The first region may be, for example, in a mesopic region.

Abstract: A method for manufacturing an organic light emitting diode display includes forming a thin-film transistor on a substrate, forming a protection layer by using a deposition method on an entire surface of the substrate, and forming an organic light emitting element on the protection layer. Forming the protection layer includes forming a first protection layer, a surface thereof including a first wrinkle, and forming a second protection layer on the first protection layer, a surface thereof including a second wrinkle. A first modulus value of the first protection layer is less than a second modulus value of the second protection layer by at least 300 MPa.
