Patent ID: 8736790

Claim:
An organic light emitting diode (OLED) display, comprising: a first substrate; a second substrate facing the first substrate; an organic light emitting element on the first substrate, the organic light emitting element including a pixel electrode, an organic emission layer, and a common electrode; a liquid crystal driving electrode facing the organic light emitting element at a lower portion of the second substrate, the liquid crystal driving electrode including a portion directly above the organic emission layer of the organic light emitting element; and a plurality of liquid crystals between the organic light emitting element and the liquid crystal driving electrode, wherein the plurality of liquid crystals is driven by the common electrode and the liquid crystal driving electrode such that the plurality of liquid crystals has optical isotropy when an electric field is not applied between the common electrode and the liquid crystal driving electrode and has optical anisotropy when the electric field is applied between the common electrode and the liquid crystal driving electrode.
