A display device is provided, which includes a light sensor in a display panel. The display device comprises a substrate having a unit pixel area and a unit light sensor area, a first electrode over the substrate, a second electrode over the first electrode, a third electrode over the second electrode, a light emitting layer in the unit pixel area and disposed between the first electrode and the second electrode, and a light active layer disposed in the unit light sensor area and disposed between the second electrode and the third electrode.

Display device with more compact light sensor

A light emitting display apparatus can include a light emitting element disposed on a substrate; an encapsulation unit disposed on the light emitting element; and a scattering film disposed between the encapsulation unit and the light emitting element, or inside the encapsulation unit, the scattering film being configured to scatter light emitted from the light emitting element.

Light emitting display apparatus

An organic light emitting display device has an optical multilayer film on an organic light emitting diode. The organic light emitting display device includes an organic light emitting element with a cathode, an anode, and an organic light emitting layer, and an optical multilayer film on the organic light emitting element. The optical multilayer film is constructed such that a full width at half maximum of light emitted from the organic light emitting element is larger than a full width at half maximum of light emitted from a structure in which the optical multilayer film is not used. The color shift depending on a viewing angle of the organic light emitting display device may be reduced to improve efficiency of the organic light emitting element.

Organic light emitting display device

A substrate for an organic light emitting display device and an organic light emitting display device are provided. The substrate to the organic light emitting display device includes a protective layer having a non-flat shape; a first electrode on the protective layer and having the non-flat shape; and a bank layer on the protective layer and the first electrode. The bank layer having an opening for exposing the first electrode. The protective layer is formed at the opening of the bank layer and a part of an area with the bank layer.

Substrate for organic light emitting display device and organic light emitting display device

The present disclosure relates to a method for manufacturing the patterned retarder used in the three-dimensional display device. The present disclosure suggests a method for manufacturing a patterned retarder comprising: defining a first retarder region and a second retarder region in the patterned retarder; forming a first polarization pattern at the first retarder region by a partial exposure process having a first exposure energy; and forming a second polarization pattern at the second retarder region by whole exposure process having a second exposure energy. By manufacturing the patterned retarder with lower exposure energy, it is possible to reduce the whole manufacturing takt time, so that the production yield can be enhanced and the production cost can be reduced.
