<P>PROBLEM TO BE SOLVED: To provide such a display plate that a display part of characters, a figure, a pattern, etc., of a second reflection part formed of luminosity microparticles changing in reflected light color between natural light and LED light can clearly be displayed even in a dark place by forming the second reflection part on a multi-layered plate comprising a transparent layer and an opaque layer, placing a first reflection member thereupon, and making the LED light incident from a portion of their outer peripheral edge. <P>SOLUTION: The display plate is constituted by forming recesses in the multi-layered plate comprising the transparent layer and opaque layer; dispersing the luminosity microparticles having reflective surfaces in the recesses; forming the second reflection part having a display part by applying colored paint, superposing the first reflection member on the reverse surface side of the multi-layered plate having the second reflection part to form a display substrate; covering the outer peripheral edge of the display plate with a reflective tape except portions thereof; arranging a plurality of LEDs at the portions which are not covered with the reflective tape; and mounting an electric circuit switching device. <P>COPYRIGHT: (C)2008,JPO&INPIT |
