Abstract:
It is an object of the invention to achieve weight saving and downsizing of an electronic apparatus, in particular a portable electronic apparatus while enlarging a display screen thereof. The invention provides an electronic apparatus using a light emitting device which includes a light emitting element, a color filter provided on either side of an anode or a cathode of the light emitting element, and two polarizers sandwiching the light emitting element and the color filter, in which the anode and the cathode transmit light, deflection angles of the two polarizers are different from each other, and light obtained from the light emitting element is white.
