According to one embodiment, a display device includes a base electrode, a rib including an aperture overlapping the base electrode, a lower electrode disposed at the aperture and electrically connected to the base electrode, a partition including a lower part disposed on the rib and an upper part projecting from a side surface of the lower part, a organic layer covering the lower electrode, and a upper electrode disposed on the organic layer. A periphery of the base electrode is covered by the rib. The base electrode is formed of a first metal material. A periphery of the lower electrode is located on the rib. The lower electrode is formed of a second metal material different from the first metal material.

A display panel and a display device are provided. The display panel includes an array substrate and a plurality of first transparent electrodes disposed on the array substrate, and a material of the first transparent electrode is an organic transparent conductive material. The display panel and the display device in the present disclosure can overcome problems that an indium tin oxide transparent electrode in a conventional flexible display device is easily broken and is easily separated from an alignment layer, thereby effectively improving the bending resistance and the stability of a flexible display panel.

Disclosed is a display device having a thin film transistor substrate, which may prevent afterimage and flicker defects by reducing the non-uniformity of an electric field. In the thin film transistor substrate, a pixel electrode includes a transparent edge electrode and a transparent inner electrode, which are spaced apart from each other with a first slit having a first width interposed therebetween, and a common electrode is exposed from the other-side end of the transparent edge electrode by a second width, which is smaller than the first width, in the width direction of a data line. As such, an inner area and an edge area in each sub pixel have uniform electric field distribution.

An OLED display panel is provided which can control the problem of shedding even in high definition panels. Metal wiring 5 which conducts with an earth line of a flexible printed substrate 15 is provided on a substrate 1. A display area 2 comprised from a plurality of OLED elements is provided at the center of the substrate 1 and four low resistance metal films 3 are provided along each of four edges of the display area 2 on a surface of insulation films 8, 10 at the periphery of the display area 2.
