A display device includes a data line transmitting a data voltage to each pixel, a power line supplying current to each pixel, wherein the data line and the power line are disposed on a substrate and extended along a first direction, a light shielding layer shielding a light emitting diode from light coming from outside, a gate line transmitting a gate voltage to each pixel and extended along a second direction intersecting the first direction, a gate insulating layer and a buffer layer disposed between the data line and the gate line, wherein the data line and the power line are disposed on a same layer as the light shielding layer.

Contact structure and display device including the same

In the contact structure according to an exemplary aspect of the present disclosure and a display device including the same, the pixel may be designed regardless of the size of the contact hole by designing a size (or an area) of the contact hole to be larger than the contact area and applying different structures depending on the characteristics of the lower layer. Therefore, the size of the contact hole is increased so that the halftone mask may be easily applied and the number of masks may be advantageously reduced. Further, a degree of freedom of metal in the pixel design is increased so that the pixel may be designed in a high resolution model and the aperture ratio is increased without having the electrode margin. The contact structure comprises: a lower layer; at least a first insulating layer on the lower layer, the first insulating layer having a predetermined contact hole to expose a part of the lower layer; and an upper layer on the first insulating layer to be in contact with the lower layer through the contact hole, wherein the contact hole has a relatively larger area than a contact area where the upper layer and the lower layer are in contact with each other.

The present disclosure is provided a display device. The display device includes subpixels and at least one scan line. The subpixels are formed on a first substrate, and each of the subpixels includes an emission area, in which a light emitting element for emitting light is disposed, and a circuit area in which a circuit for driving the light emitting element is disposed. The at least one scan line may be disposed on the circuit area in a horizontal direction. The at least one scan line may include: an upper scan line and a lower scan line spaced apart from each other; and a scan connection line positioned between the upper scan line and the lower scan line and electrically connecting the upper scan line and the lower scan line.

Display device

The present disclosure relates to a display device including a light emitting element display. The present disclosure suggests a flat panel display comprising: a substrate; a driving element disposed on a first surface of the substrate; an organic light emitting diode disposed on a second surface of the substrate; a through-hole penetrating the substrate from the front surface to the rear surface; and a connecting electrode filling the through-hole for linking the driving element to the organic light emitting diode.
