Abstract: A display device includes a display panel divided into a display area and a non-display area, and an input sensing unit disposed on the display panel and divided into an active area and a non-active area. The input sensing unit includes a plurality of sensing electrodes overlapping the active area and including a plurality of first sensing electrodes extending in a first direction, and a plurality of second sensing electrodes extending in a second direction crossing the first direction, a plurality of first trace lines respectively connected to the plurality of first sensing electrodes and including an inside portion overlapping the active area, and a dummy electrode unit overlapping the inside portion in the first direction. The dummy electrode unit is adjacent to the plurality of sensing electrodes in the second direction and does not overlap the plurality of sensing electrodes in the first direction.

Abstract: A display panel includes a base layer having a first region and a bent second region. An inorganic layer is disposed on the base layer. A lower groove is formed within the inorganic layer and overlaps the second region. A first thin-film transistor is disposed on the inorganic layer and includes a silicon semiconductor pattern overlapping the first region. A second thin-film transistor is disposed on the inorganic layer and includes an oxide semiconductor pattern overlapping the first region. Insulating layers overlap the first and second regions. An upper groove is formed within the insulating layers. A signal line electrically connects the second thin-film transistor. An organic layer overlaps the first and second regions and is disposed in the lower and upper grooves. A luminescent device is disposed on the organic layer and overlaps the first region.
