A display device includes: a first electrode; a second electrode; and an emitting material layer which is interposed between the first electrode and the second electrode, the emitting material layer being doped with an electric charge transport material of which content varies along a thickness direction and comprising a plurality of sub-layers staked in sequence.

Display device

A droplet ejecting apparatus, method of forming a thin film, and a substrate for a display device, wherein a droplet ejecting apparatus includes a first ejecting unit ejecting a first droplet on a substrate, a second ejecting unit ejecting a second droplet on the substrate along a path defined by a movement of the first ejecting unit, and a transporting unit connected with the first ejecting unit and the second ejecting unit to transport the first ejecting unit and the second ejecting unit.

Droplet ejecting apparatus, method of forming a thin film, and substrate for a display device

An electronic display apparatus includes a substrate, pixels and light sensing parts. The substrate includes a display region and a peripheral region adjacent the display region, and the substrate includes a plurality of gate lines extended in a first direction and a plurality of data lines extended in a second direction that is substantially perpendicular to the first direction. The pixels defined by each of the data and gate lines are formed in the display region to display an image. The light sensing part is formed in the peripheral region, and the light sensing part senses an intensity of an ambient light. The light sensing part that senses an intensity of an ambient light is formed on the array substrate, so that a luminance of the display apparatus may be adjusted in accordance with the intensity of the ambient light.
