Abstract
An organic light emitting diode display device includes a plurality of organic light emitting diode elements that are arranged in a matrix; a plurality of protective layers, each of the protective layers covering at least one of the organic light emitting diode elements; and a stress relaxation layer that is formed between the protective layers, for relaxing a stress caused by the protective layers. The stress relaxation layer may surround the protective layer. Moreover, the stress relaxation layer may be made of a shading material, and serve as a mask for forming the organic light emitting diode elements.
