Display device

摘要

An image display device includes phosphor layers which are formed on an inner surface of a light transmitting face plate, a black matrix film which is formed on the inner surface of the face plate in a state that the black matrix film defines the phosphor layers into phosphor layers of respective colors, and electron beam sources which are arranged in the inside of the evacuated envelope in a state that the electron beam sources face the phosphor layers in an opposed manner and irradiates electron beams to the phosphor layers. An area occupying ratio of the black matrix film as viewed from an image display screen side of the face plate is set within the range of 60% to 95%.
