Display device

A display device, comprising:

• a first substrate;
• a data line disposed on the first substrate and extending along a data-line-extension direction;
• and
• three pixel units disposed on the first substrate, each of the three pixel units comprising:
• a transistor disposed on the first substrate;
• a first insulating layer disposed on the transistor, wherein the first insulating layer comprises an upper surface, and at least a via hole passing through the first insulating layer;
• a first electrode disposed on the first insulating layer, wherein the first electrode electrically connects to the transistor through the via hole;
• a pixel defining layer disposed on the first electrode and the first insulating layer, wherein the pixel defining layer exposes a part of the first electrode to define a light emitting region;
• a light emitting layer disposed on the first electrode;
• and
• a second electrode disposed on the light emitting layer;
• wherein, in each of the three pixel units, the via hole has a first outline on the upper surface of the first insulating layer, and the light emitting region has a second outline on the upper surface of the first insulating layer;
• and
• wherein the first outline has a first point, the second outline has a second point, a minimum distance between the first outline and the second outline is a distance between the first point and the second point, a first extension direction is an extending direction of a connecting line between the first point and the second point in that pixel unit,
• wherein, in a normal direction view of the first substrate, at least one pixel unit of the three pixel units partially overlaps the data line,
• wherein, in at least two pixel units of the three pixel units, each second outline has a long axis and a short axis, the directions of the long axis being different for each of the at least two pixel units, further wherein each of the at least two pixel units emits the same color, and
• wherein, in a normal direction view of the first substrate, a width of the first electrode continuously increases between the first point and the second point in each of the two pixel units.
