摘要:
An electroluminescence (EL) display device is disclosed with a microlens layer positioned between a light-emission layer and a color converting layer or a color filter layer. The microlens layer can be formed separately or integrally with an electrode of the EL display device. Light emitted from the light-emitting layer passes through an electrode and then through the microlens layer, which has a higher refractive index than the electrode to focus light in a predetermined direction. The light then passes through the color converting layer or a color filter layer to emit red, green, or blue light from the device. The microlens layer and color converting layer or color filter layer can be disposed for either active matrix or passive matrix, and for either a top-emission type, bottom-emission type, or dual emission type EL display device for improved external light coupling efficiency and brightness.
