Abstract

PURPOSE:To obtain a colored display having a high luminance by allowing a luminous phosphor to emit a light beam by ultraviolet rays which are emitted from an ultraviolet ray emitting source. CONSTITUTION:The titled device is provided with a liquid crystal cell, an ultraviolet ray emitting source 39 which is placed in the back side of this liquid crystal cell, and a luminous phosphor 36 which has been placed on an optical path of ultraviolet rays emitted from this ultraviolet ray emitting source 39. By driving a desired TFT 22 by driving a driving circuit board, and setting a picture element in this position, to an applied state, a liquid crystal 33 in this position is set to a light transmissive state. On the other hand, in the ultraviolet emitting source 39, ultraviolet rays are emitted, and this ultraviolet rays are made incident on the luminous phosphor 36 through an ultraviolet ray transmission visible light reflecting filter glass substrate 34. When the ultraviolet rays from the ultra violet ray emitting source 39 are made incident, the ultraviolet rays themselves are colored by the luminous phosphor 36 for emitting the light beams of the respective colors, therefore, the colored light beam of almost the same quantity as the light quantity of the ultraviolet rays emitted from the ultraviolet ray emitting source 39 can be obtained in the surface side. In such a way, a color display having a high luminance is obtained.
