The present invention provides a diffusely-reflecting polarizer havinga first polymer which is amorphous and having a birefringence of less than about 0. A dielectric mirror which is selective in wavelength is provided between organic EL elements, and the number of times especially blue light emission from an organic EL element is transmitted through an electrode having a light-transmitting property is reduced as much as possible, so that attenuation of light is suppressed. The row decoder includes latch circuits and a drive circuit. The composite material with the matrix material and inclusions allows the composite material to be acoustically dissipating with a stiffness in which the energy of forces associated with undersea platforms is resisted.
