An organic electroluminescence structure comprises a first substrate, an organic electroluminescence device, and a control device. Forming either a lifting layer under the control device or a recess under the organic electroluminescence device, or forming both of them, creates a difference between their tops, in order to reduce the dark spots and promote the yield of the end product. The lifting layer preferably has a thickness greater than about 0.5 micro meters and the recess has a depth ranges of about 0.1 micro meters to about 100 micro meters. Alternatively, the height difference between the upper surfaces of the control device and the organic electroluminescence device is controlled to be greater than about 2 micro meters or substantially equal to 2 micro meters.

A self-emissive display device. The display device comprises a substrate having a pixel region for displaying one of the primary colors. An organic electroluminescent multi-layer structure is disposed in the pixel region of the substrate. The organic electroluminescent multi-layer structure comprises a first micro-cavity portion and a second micro-cavity portion adjacent thereto. The first micro-cavity portion comprises an organic layer for light-emitting and a first film for determining light wavelength shift of the first micro-cavity portion. The second micro-cavity portion comprises the organic layer for light-emitting and a second film for determining light wavelength shift of the second micro-cavity portion. The first and second films have different optical lengths, such that the first and second micro-cavity portions provide opposite directions of the light wavelength shift.

An organic electroluminescence device and a method for reducing lateral current leakage thereof are provided. The organic electroluminescence device comprises a cathode, an anode, and an organic electroluminescence unit disposed therebetween. The organic electroluminescence unit comprises a light-emitting layer and a hole-injecting layer (HIL). The HIL possesses a sufficient resistance achieved by adjusting the thickness of the HIL and/or the concentration(s) and/or species of the conductive dopant(s) in the HIL.
