Abstract

The invention relates to a display device that includes: a display layer having a display area including a plurality of pixel areas and a peripheral area at least partially surrounding the display area; and a cover layer disposed on the display layer to encapsulate the display area. The cover layer includes: a light blocking portion overlapping the display area and the peripheral area and including a plurality of openings to transmit light from the plurality of pixel areas and to block light in the peripheral area; a first protrusion disposed on the light blocking portion in the peripheral area and surrounding the display area; and an overcoating layer covering the display area and contacting a lateral surface of the first protrusion.

Description

technical field [0001] Exemplary embodiments of the present disclosure relate generally to a display device and a method for manufacturing a display device, and more particularly, to a display device including an encapsulation layer and a photomask process without using a photomask that would damage a light emitting element such as an organic light emitting diode. A method of manufacturing a display device in the case of. Background technique [0002] An organic light emitting diode display device includes two electrodes and a light emitting layer disposed between the two electrodes, and electrons injected from one electrode and holes injected from the other electrode are combined with each other in the light emitting layer to generate excitons. The generated excitons transition from an excited state to a ground state, releasing energy to emit light. [0003] An organic light emitting diode display device includes a plurality of pixels each including an organic light emitti...
