Abstract: Disclosed is a display device which may achieve process simplification and cost reduction. The display device having touch sensors includes display pads arranged in a non-active area on a substrate and having a multilayer structure, an uppermost layer of the display pads is formed of a different material from conductive layers included in the touch sensors arranged on an encapsulation unit, and, thus, damage to the display pads during formation of the touch sensors may be prevented, process margin may be increased and high resolution may be implemented. Further, the touch sensors are arranged on the encapsulation unit without a separate attachment process and, thus, process simplification and cost reduction of the display device may be achieved.

Abstract: Disclosed are an organic light emitting display device to improve optical efficiency and prevent deterioration in reliability of thin film transistors, and a method of manufacturing the same. The organic light emitting display device includes a mirror wall which is disposed on a substrate such that the mirror wall surrounds a light emitting area of each sub-pixel where a light emitting element is disposed, thus preventing total reflection of light produced in the light emitting element and improving optical efficiency by reflecting light travelling toward a non-emitting area to be directed to the light emitting area.

Abstract: A display apparatus including two lines is provided. The two lines may extend in a first direction. A light-emitting device may be disposed between the two lines. Each line may be bent or extended in the direction of the device substrate which supports the light-emitting device. Thus, in the display apparatus, mixing of light emitted to the outside through the device substrate may be prevented. Therefore, in the display apparatus, the quality of realized image may be improved.
