Abstract: A display device includes a display part formed on a base layer, the display part including a plurality of pixels, and a sensor part disposed on the display part, the sensor part including a conductive pattern layer and a cover layer disposed on the conductive pattern layer. The conductive pattern layer forms a first sensing electrode and a second sensing electrode, and includes an edge portion forming a disconnection area. The cover layer includes a first cover layer overlapping the disconnection area in a plan view.

Abstract: A display device comprises a first pixel and a second pixel adjacent in a first direction, and a sensor a first conductive pattern layer and a second conductive pattern layer. The pixels include a first sub-pixel forming a first sub-pixel area emitting a first color, a second sub-pixel forming a second sub-pixel area emitting a second color, and a third sub-pixel forming a third sub-pixel area emitting a third color. The third sub-pixels of the first and second pixels are adjacent in the first direction. The first and second sub-pixels of the first pixel and the second pixel are adjacent in the first direction. The sensor comprises a first sensing electrode and a second sensing electrode, each comprising cells and bridges. A second bridge is not between the first and second sub-pixels of the first and second pixels, and extends between the third sub-pixels of the first and second pixels.

Abstract: A display device includes a display part including multiple unit pixels, each of the unit pixels including multiple display pixels and a light sensing pixel, multiple touch electrodes disposed between the display pixels and the light sensing pixel, surrounding circumferences of the display pixels and the light sensing pixel, and sensing a touch, and a main driving circuit sensing a fingerprint by the light sensing pixel. The light sensing pixel in one of the unit pixels and the light sensing pixel in another one of the unit pixels have different light transmissivities for external light, and the main driving circuit analyzes light sensing signals of the light sensing pixels having the different light transmissivities to detect a luminance value or an illuminance value of the external light.
