Abstract
A light emitting element is provided, including a first electrode layer, a second electrode layer, and an organic light emitting layer sandwiched between the first electrode layer and the second electrode layer. The organic light emitting layer is patterned to include a plurality of light emitting blocks with different densities. In an embodiment, the light emitting blocks are divided into a plurality of light emitting block groups that are arranged in an alternate manner. In another embodiment, a light emitting element includes a first electrode layer, a first organic light emitting layer, a charge generating layer, a second organic light emitting layer, and a second electrode layer sequentially stacked on one another. The first and second organic light emitting layer are patterned to form a plurality of first and second light emitting blocks with different densities, respectively. Thus, the light emitting element generates full-color, gray-scale, three-dimensional, or dynamic images.
