Abstract: A display device includes an array substrate defined with a plurality of pixel structures arranged in an array. Each of the pixel structures includes a semiconductor layer disposed over a substrate and a first metal layer disposed over the substrate. The pixel structure includes a first insulating layer disposed over the semiconductor layer, having a first opening exposing a top surface of the semiconductor layer and a sidewall surface of the first insulating layer. The pixel structure includes a metal pad disposed over the first insulating layer, being formed over the top surface of the semiconductor layer and the sidewall surface of the first insulating layer through the first opening. The pixel structure includes a second insulating layer disposed over the metal pad and the first insulating layer, having a second opening exposing the metal pad over the sidewall surface of the first insulating layer.

Abstract: An element substrate is provided, including a substrate, a metal layer, a planarization layer and a first conductive layer. The metal layer is disposed on the substrate. The planarization layer is located on the metal layer, wherein the planarization layer includes a contact hole, the contact hole has a continuous wall and a bottom, the bottom exposes the metal layer, and the bottom of the contact hole has a first width. The first conductive layer is located on the planarization layer, wherein the first conductive layer includes an opening, the opening exposes the contact hole, and the opening has a second width above the contact hole, wherein the relationship of the first width and the second width is modified to decrease illumination loss and to prevent problems of shot-circuiting and insufficient capacitance.

Abstract: A display device includes a first substrate and an insulating layer over the first substrate. The display device further includes a semiconductor layer over the insulating layer and a dielectric layer over the semiconductor layer, having an opening partially exposing the semiconductor layer and the insulating layer, wherein the opening has a first width along a first direction. In addition, the display device further includes a conductive line extending over the dielectric layer along a second direction that is different from the first direction and filling the opening to electrically connect to the semiconductor layer exposed by the opening. The conductive line includes a first portion over a top surface of the dielectric layer and a second portion in the opening. The first portion of the conductive line has a second width along the first direction. The first width is greater than the second width.
