A display device includes: a substrate; a polycrystalline silicon film on the substrate; and a first buffer film between the substrate and the polycrystalline silicon film and having one surface contacting the polycrystalline silicon film and another surface opposite to the one surface, wherein the one surface of the first buffer film has a first root mean square (RMS) roughness range, and the first RMS roughness range is 1.5 nm or less.

Display device

A display device comprises a substrate; a circuit array layer comprising pixel drivers, data lines, first dummy lines, and second dummy lines; and a light emitting array layer. The display area comprises middle, first side, and second side regions. The data lines comprise first, second, and third data lines disposed in the middle, first side, and second side regions, respectively. The first dummy lines comprise a first data detour line disposed in the first side region and adjacent to a part of the second data line, and auxiliary lines. The second dummy lines comprise a second data detour line configured to connect the first data detour line to the third data line, and additional lines. The auxiliary lines comprise a bias auxiliary line to which a bias power is applied; and a second power auxiliary line to which a second power is applied.

A display device includes a first thin film transistor disposed on a substrate. A first insulating interlayer covers the first thin film transistor. An active pattern is disposed on the first insulating interlayer. The active pattern includes indium-gallium-zinc oxide (IGZO) having a thickness in a range of about 150 &#x212b; to about 400 &#x212b;. A gate insulation layer covers the active pattern. A gate pattern is disposed on the gate insulation layer. A second insulating interlayer covers the gate pattern.

A display device according to an embodiment of the present disclosure includes a display panel including a display region and a non-display region, and a sensor unit which is disposed on the display panel and includes a sensing region and a non-sensing region. The sensor unit includes a touch sensor unit which detects a touch input in the sensing region and a photo sensor unit which detects ambient illuminance.
