  • Patent number: 11435858
    Abstract: A display device and a touch sensor, the display device including a first substrate in which a display area and a peripheral area around the display area are defined; an element layer which is located on the first substrate and comprises a first light emitting element located in the display area and a second light emitting element at least partially located in the peripheral area; and a touch sensor which is located on the element layer. The touch sensor includes: a touch electrode portion which is located in the display area and overlaps the first light emitting element; a touch signal line which is located in the peripheral area and is connected to the touch electrode portion; and a light transmission control pattern portion which is located in the peripheral area, overlaps the second light emitting element, and extends along a boundary between the display area and the peripheral area.
