摘要： A display device includes unit pixels, each unit pixel including display pixels and a light sensing pixel, touch electrodes sensing a touch and, when viewed in a plan view, surrounding a first region where each of at least two display pixels is disposed and a second region where the light sensing pixel and one of the display pixels that is different from the at least two display pixels are disposed, and a main driving circuit receiving a light sensing signal from the light sensing pixel and sensing a fingerprint by analyzing the light sensing signal. The touch electrodes define at least one open area in which no touch electrode is formed between the light sensing pixel and at least one display pixel in each unit pixel.

摘要： A display device includes a fingerprint sensor layer that receives light reflected by an external object; a substrate disposed on the fingerprint sensor layer; an optical pattern layer disposed on the substrate and that includes a light blocking portion and a light transmitting portion that passes through the light blocking portion in one direction; a first light transmitting layer with a first refractive index and that is disposed on the light blocking portion; a second light transmitting layer with a second refractive index different from the first refractive index and that is disposed on the first light transmitting layer; and a light emitting element layer disposed on the second light transmitting layer.
