Abstract
An organic light emitting device, wherein a color filter is formed in a display device displaying a color by using a micro-cavity effect, and grooves with a concave lens shape are formed In the surface of the color filter. As a result, the amount of emitted light is increased and the viewing angle is improved due to the grooves with the concave lens shape.
Claims20
