摘要:
In the present invention, there is disclosed a reflective mirror whose contrast or resolution performance is equal to that of a surface mirror of a glass mirror for general use and which does not have any problem in reliability of resistance to environment and whose color shift or brightness performance is inhibited from being degraded. For this, in the present invention, a reflective film is formed on a glass substrate by use of silver mirror reaction, and a topcoat is formed of a colorless/transparent resin. At this time, a wavelength of a crest of a ripple indicated by a reflectance characteristic is constituted to substantially agree with that of a green luminescent line. Accordingly, a back projection type video display device which is satisfactory in the contrast or resolution performance can be prepared.

According to the present invention, the amount of usage of a heat conductive member for fixing a self-luminous flat display panel to a metallic chassis member disposed at the back of the display panel is reduced in the thickness direction as well as in the surface direction. The invention further provides a technique for efficiently radiating heat from the display panel, suppressing cost increase. To this end, in the invention, the heat conductive member is a hot-melt adhesive having adhesion at room temperature and filled with a heat conduction imparting agent, and the display panel is fixed to the chassis member by a plurality of heat conducting sections of the heat conductive member formed discretely ranging from 0.3 to 0.8 mm in thickness.

A back substrate has a plurality of electron emission elements. A display substrate comprises an optically transparent substrate disposed opposite to the back substrate; an accelerating electrode formed on the inner face of the optically transparent substrate for accelerating electron beams emitted from the electron emission elements; and luminescent materials excited by the electron beams to emit light toward the outer face of the optically transparent substrate. A frame member supports the back substrate and display substrate on their peripheries. A vacuum chamber is defined by the back substrate, display substrate, and frame member. A conductor electrically connected to the accelerating electrode is drawn out to the outside of the vacuum chamber. A high voltage connector for supplying an accelerating voltage to the conductor is removably connected to the conductor.
