    • An electroluminescent device includes an R pixel which emits red light, a G pixel which emits green light, and a B pixel which emits blue light, and an insulator laminated film. In the electroluminescent device, each pixel has, at least, a pair of electrodes of which one is a light transmitting electrode and a light-emitting layer which is inserted between the electrodes, and emits light by being supplied with electric energy. The insulator laminated film is formed on the surface of the light transmitting electrode opposite to the light-emitting layer and has a plurality of low refractive-index layers each formed of a light transmitting insulator and a plurality of high refractive-index layers each formed of a light transmitting insulator having a refractive index higher than that of the low refractive-index layer, which are alternately laminated. Each low refractive-index layer is formed over the entire luminescent region of the R pixel, the G pixel, and the B pixel and has a constant thickness even in any one of regions which overlap the R pixel, the G pixel, and the B pixel. Each high refractive-index layer is formed over the entire luminescent region of the R pixel, the G pixel, and the B pixel and has a constant thickness even in any one of regions which overlap the R pixel, the G pixel, and the B pixel. The plurality of the low refractive-index layers have different thicknesses, and the plurality of the high refractive-index layers have different thicknesses. The thicknesses of the low refractive-index layers and the high refractive-index layers are determined such that, when the light-emitting layer emits light, light having an intensity higher than that of the case of not having the insulator laminated film is emitted from the insulator laminated film by reflection at, at least, the interface between the light transmitting electrode and the insulator laminated film and the interfaces between the low refractive-index layers and the high refractive-index layers, even in a luminescence peak wavelength of any one of the R pixel, the G pixel, and the B pixel.

    • An exposure apparatus includes a line head and a rotatable photosensitive drum, which is exposed by light from the line head. The line head includes N (“N” being 2 or greater) EL element column. In each EL element column, the area S of a light-emitting pixel of the EL element is constant within a corresponding column. When the column number of the EL element columns is from 1 to N, the area of the light-emitting pixel of the EL element in each column is Si=S1/(2n−1) (where, “i” is the column number of each EL element column and a natural number from 1 to N, and “S1” is the area of the light-emitting pixel of the EL element of a first column). One or more EL elements selected from N EL elements within the N EL element columns perform exposure on the same unit drawing region on the photosensitive drum.
