Abstract:
1. An organic EL display comprising: an organic EL display panel to have a metal electrode; a first polarizing plate on the organic EL display panel; and a second polarizing plate on the first polarizing plate to have a polarization characteristic of absorbing light in a high light efficiency wavelength range more than light in a low light efficiency wavelength range, wherein the first polarizing plate is converting a linearly polarized light into a circularly polarized or converting a circularly polarized light into a linearly polarized light and wherein polarization efficiency and transmittance of the second polarizing plate are differently set per a red wavelength, a green wavelength and a blue wavelength, respectively and the second polarizing plate has high transmittance and low polarization efficiency in a blue wavelength rather than the green and red wavelengths.
