Flat-panel display apparatus

Abstract

This invention provides a flat-panel display apparatus adapted to reduce the electric charges stored into fluorescent materials, and to allow spacers to be arranged easily and accurately, and capable of displaying high-quality images by improving color purity of the colored light emitted toward the viewing side. The display apparatus according to this invention has a rear substrate 1 including an electrical insulating substrate 10 on which are formed a large number of cold-cathode elements 19 for emitting electrons, a display substrate 101 including a light-transmissive substrate 110 which is disposed facing the rear substrate 1 and on which are formed the fluorescent materials 111 that emit light when excited by the electron beams sent from the cold-cathode elements 19, and a frame member 116. A metallic sheet 120 in which a large number of fine-structured holes 122 each containing one fluorescent material 111 and for forming a light-emitting region are provided in matrix form is disposed on the light-transmissive substrate 110. Color filters that transmit the rays-of-light of desired colors, emitted from associated fluorescent materials, are provided between the light-transmissive substrate containing the fine-structured holes, and the fluorescent materials.
