Abstract
On a main face of a substrate, organic EL light emitting layers are formed by stacking first electrodes for respective pixels, an organic EL layer having a white light emitting function formed above the first electrodes to cover the first electrodes in common, and a second electrode formed such that the second electrode covers the organic EL layer in common in this order, and light emitted from the organic EL layer is irradiated to the second electrode side. Above the second electrode, a color converting filter, which converts the white light emitted from the organic EL light emitting layer to a given color and is applied by coating using a wet process, is formed for every pixel, and a protective layer, which prevents the deterioration of the light emitting layer attributed to a coating material of the color filter, is provided between the second electrode and the color converting filter.
