Abstract:
Each pixel includes a region where a lower reflection film is not present. In each pixel, there is a region where a microcavity structure is formed between a counter electrode and a lower reflection film and another region where the microcavity structure is not formed. The regions differentiated in cavity length can differently enhance the peak wavelength so as to improve the viewing angle dependence. Furthermore, in each of R, G, and B light emitting pixels, the area ratio of a region where the microcavity structure is present and another region where the microcavity structure is not present can be adjusted so as to eliminate the differences caused by the microcavity structure.
