    Abstract: Disclosed is a display device with integrated touch screen, which can prevent a first touch electrode or a second touch electrode from being short-circuited with a bridge electrode through an opening. The display device includes first electrodes on a first substrate, a light emitting layer on the first electrodes, a second electrode on the light emitting layer, an encapsulation layer on the second electrode, a bridge electrode and a dummy electrode on the encapsulation layer, an insulation layer covering the bridge electrode and the dummy electrode, and a first touch electrode and a second touch electrode on the insulation layer. The first touch electrode is electrically connected to the bridge electrode, and bridge electrode is spaced apart from the dummy electrode.

    Abstract: A fabrication method is described which reduces processes of fabricating display devices such as an in-cell type display device. The display device includes: a gate line over a substrate; a data line over the substrate; a thin-film-transistor (TFT) including a drain electrode and a source electrode, the TFT located at a pixel defined by an intersection between the gate line and the data line; a first electrode layer located to be spaced apart from one of the source electrode and the drain electrode of the TFT; and a second electrode and a connection pattern over the first electrode, both the second electrode and the connection pattern of a same material, the connection pattern connecting one of the source electrode or the drain electrode of the TFT to the first electrode.

    Abstract: A light emission element includes a first semiconductor layer, a light emission layer, and a second semiconductor layer. The first semiconductor layer in the light emission portion is provided with a concave portion having a concave shape. The light emission layer and the second semiconductor layer disposed on the first semiconductor layer are also disposed along the concave shape of the concave portion. The light emitting layer disposed along the shape of the concave portion emits light by electrons and holes injected from the first semiconductor layer and the second semiconductor layer. Further, the light path of the light emitted according to the concave shape is adjusted. Therefore, a light emission element having improved light efficiency and a display device using the same can be provided.
