    摘要: A number of LEDs 6 are vertically and horizontally arrayed on a printed circuit board 5, thereby forming a display surface. Switches 7 for turning on or off the LEDs 6 and keeping them in an on or off state are provided at locations corresponding to or close to the LEDs 6. With this construction, the LEDs 6 can be turned on or off directly from the display surface.
