Abstract
A display device including a first substrate; a display element layer on the first substrate; a second substrate on the display element layer; and a spacer layer between the first substrate and the second substrate.
Claims16
A display device, comprising:
- a first substrate including a thin film transistor layer;
- a display element layer on the first substrate;
- a second substrate on the display element layer;
- and
- a spacer layer between the first substrate and the second substrate,
- wherein the spacer layer includes:
- a first spacer electrode on the first substrate,
- a second spacer electrode on the second substrate and facing the first spacer electrode, and
- an electroactive polymer layer between the first spacer electrode and the second spacer electrode, a distance between the first substrate and the second substrate varying in response to a voltage applied between the first spacer electrode and the second spacer electrode such that the display device has a desired thickness that is controllable in response to the voltage applied between the first spacer electrode and the second spacer electrode.
