Abstract: A head-mounted display device includes a display, a lens group and an actuator. The display is used for generating an image light beam. The lens group is disposed between the display and a target area and is adapted to focus the image light beam to form a display image in the target area. The actuator is coupled to the display or the lens group to periodically move the display or the lens group on a plane.

Abstract: A display panel includes a TFT substrate, which includes a substrate, a plurality of scan lines, a plurality of data lines, and a first intermediate layer. The scan lines are disposed on the substrate along a first direction, and the scan lines are intersected with the data lines to define a plurality of sub-pixel units. The sub-pixel units include a first sub-pixel unit and a second sub-pixel unit. The first sub-pixel unit has a first light transmission area and a first component installation area, and the second sub-pixel unit has a second light transmission area and a second component installation area. The first intermediate layer is disposed on the substrate and has an opening. The opening is at least partially overlapped with the first light transmission area, and is at least partially overlapped with the second light transmission area.

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 panel including a first substrate and a second substrate disposed is provided. The first substrate includes a first data line, a second data line, and a third data line parallel with one another, and a first scan line and a second scan line parallel with each other.

The first scan line, the second scan line, the second data line and the third data line define a second sub-pixel. The first sub-pixel includes a first pixel electrode. The second sub-pixel includes a second pixel electrode. A first interval between the first pixel electrode and the second data line is larger than a second interval between the second pixel electrode and the second data line.
