Abstract
An organic light emitting display includes a base substrate, a driving transistor arranged on the base substrate, a first electrode electrically connected to the driving transistor, an organic light emitting layer arranged on the first electrode to generate a light, a second electrode arranged on the organic light emitting layer, an opposite substrate facing the base substrate and including micro-lenses to disperse the light generated by the organic light emitting layer, and a sub-electrode arranged on at least one of the micro-lenses, the sub-electrode making contact with the second electrode to be electrically connected to the second electrode.
Claims9
An organic light emitting display comprising:
- a base substrate;
- a driving transistor arranged on the base substrate;
- a first electrode electrically connected to the driving transistor;
- an organic light emitting layer arranged on the first electrode to generate a light;
- a second electrode arranged on the organic light emitting layer;
- an opposite substrate facing the base substrate and including micro-lenses to disperse the light generated by the organic light emitting layer, wherein at least one of the micro-lenses has a thickness that differs from another one of the micro-lenses;
- and
- a sub-electrode arranged on at least one of the micro-lenses, the sub-electrode making contact with the second electrode to be electrically connected to the second electrode
- wherein the base substrate comprises a plurality of pixel areas, the first electrode is arranged in each pixel area, and the sub-electrode is arranged between adjacent pixel areas in a plan view,
- wherein the micro-lenses comprise:
- first micro-lenses protruding from the opposite substrate and each corresponding to a respective one of the pixel areas, wherein each of the first micro-lenses has a first thickness;
- and
- second micro-lenses protruding from the opposite substrate and corresponding to areas between adjacent pixel areas, wherein each of the second micro-lenses has a second thickness that is thicker than the first thickness, and wherein the sub-electrode is arranged on the second micro-lenses.
A substrate opposing a display substrate of an organic light emitting display, the opposing substrate comprising:
- a transparent substrate, wherein one surface of the transparent substrate includes a first plurality of lenses disposed to face respective pixel areas of the display substrate and a second plurality of lenses disposed to face respective spaces between the pixel areas, wherein the first plurality of lenses have a different thickness from the second plurality of lenses;
- and
- a plurality of sub-electrodes contacting with and covering a part of a respective one of the second plurality of lenses,
- wherein the sub-electrodes are configured to make an electrical connection with a transparent conductive material of the display substrate.
