Abstract:
D={(2πm+φL+φU)/4π}λ is satisfied when an optical path length between a reflecting layer and pixel electrode and a counter electrode is D, a phase shift in reflection in the reflecting layer and pixel electrode is φL, a phase shift in reflection in the counter electrode is φU, a peak wavelength of a standing wave generated between the reflecting layer and pixel electrode, and the counter electrode is λ, and an integer of 2 or less is m. Here, among red, green, and blue pixel reflecting layer and pixel electrode, at least one reflecting layer and pixel electrode may be made of a different metal material from that of the other reflecting layer and pixel electrodes.
