  • Light-emitting display device provided with light-emitting portions having varying areas
    Patent number: 7443093
    Abstract: A display device for increasing a lifetime includes a base substrate having a plurality of pixel regions, a plurality of first electrodes formed on the pixel regions, a light emitting layer including first, second and third light emitting portions to generate first, second and third lights, a second electrode that is electrically coupled to the light emitting layer. At least two of the first, second and third light emitting portions have different areas from each other. The areas of the light emitting portions are determined by reference lifetimes. Therefore, the lifetime for the display device is increased.
