Each of the first emission area and the second emission area includes a first region overlapping with the corresponding upper opening and a second region disposed outside the upper openings. Thus, the quality of an image generated by the display apparatus and shared with users located in different directions is improved.

There is provided a TFT backplane having at least one TFT with oxide active layer and at least one TFT with poly-silicon active layer. In the embodiments of the present disclosure, at least one of the TFTs implementing the circuit of pixels in the active area is an oxide TFT (i.e., TFT with oxide semiconductor) while at least one of the TFTs implementing the driving circuit next to the active area is a LTPS TFT (i.e., TFT with poly-Si semiconductor).

A display device (100) presented herein includes a substrate (110) including a display area (A/A) and a non-display area (N/A) surrounding the display area (A/A), a plurality of pixels (PX) disposed in the display area (A/A) and including a light emitting element (130) and a driving transistor (120), at least one dam (DAM1, DAM2, DAM3) disposed in the non-display area (N/A), an organic optical layer (141, 241) covering the plurality of pixels (PX), and at least one blocking pattern (CP1, CP2) disposed in the non-display area (N/A) and penetrating the organic optical layer (141, 241).

A display device can include a display panel (150) including subpixels having light-emitting elements, a data driver (140) configured to supply a data voltage (Vdata) or a park voltage (Vark) to the subpixels through a data line, and a timing controller (120) configured to control the data driver and provide a park voltage control value (TVPark) to the data driver. The data driver generates the park voltage based on the park voltage control value.

A display device is provided showing, relative to conventional devices, improved performance after thermal degradation. The display device provides a reduced difference between luminance of a degraded device and luminance of a non-degraded device at extreme viewing angles, where this difference cannot be fully addressed by front compensation. Improvement over display devices having subpixels disposed in a regular two dimensional array is accomplished by offsetting a portion of subpixel light-emitting areas along a critical dimension within the plane of a flat screen relative to corresponding subpixel lenses, a design that compensates for shrinkage in subpixel light-emitting areas in degraded displays.

A display device in which each of a plurality of sub-pixels includes a thin film transistor including a semiconductor layer, and an equipotential line is disposed on the same layer as the semiconductor layer and includes the same material as the semiconductor layer.

A light emitting display apparatus according to one or more embodiments of the present disclosure may include a substrate on which a display area and a pad area are disposed, an encapsulation portion extending from the display area toward the pad area on the substrate, at least one inorganic insulating layer disposed on the encapsulation portion, a pad electrode disposed in the pad area on the substrate and electrically connected to respective signal link lines, and a pad cover portion configured to cover at least a portion of the pad electrode in the pad area, the at least one inorganic insulating layer may include an extension pattern portion configured to overlap an end of the pad cover portion.
