Abstract:
1. An organic EL display device comprising an active matrix portion in which a plurality of organic EL light emitting elements are arranged in the inside of a main face of a substrate, and a sealing portion which seals the active matrix portion, wherein, each organic EL light emitting element includes one of a plurality of first electrodes which are formed above the main face of the substrate, an organic EL layer which is formed in a state that the organic EL layer covers the plurality of first electrodes in common, and a second electrode which is formed above the organic EL layer in a state that the second electrode is formed in common with the plurality of organic EL light emitting elements, and light emitted from the organic EL layer is irradiated to the second electrode side, and wherein the active matrix portion further comprises: wavelength converting filters which convert a wavelength of light emitted from the organic EL layer to a given wavelength and which are formed above the second electrode for every organic EL light emitting element by coating in a wet process, a color filter, which selectively allows light of the given wavelength to pass, wherein said color filter is formed above at least one of the wavelength converting filters to receive light from the at least one of the wavelength converting filters, which received light corresponds to the light emitted from the organic EL layer which has been shifted by the at least one of the wavelength converting filters to the given wavelength for every organic EL light emitting element by coating in a wet process, a first protective layer which suppresses the deterioration of the organic EL layer attributed to a coating material of the wavelength converting filter and which is provided between the second electrode and the wavelength converting filter, and a second protective layer which suppresses the deterioration of the organic EL layer attributed to a coating material of the color filter and which is provided between the wavelength converting filter and the color filter, wherein the active matrix portion of the substrate is sealed by the sealing portion, and wherein said color filter is directly formed on said second protective layer of said substrate.
