Abstract
A display has light emitting elements, a first driver, a power source, and a second driver. Each light emitting element includes 'n' emission layers formed one over another to form a color dot in each pixel. The first driver drives the emission layers to emit light or no light. The power source passes a current through the first driver to the light emitting element. The second driver individually weights the n emission layers and makes the emission layers emit light so that each dot may express a gradation level.
