Abstract
On the front surface of a single electroluminescent panel, there are provided a display panel, such as a liquid crystal display panel, for controlling transmission of light to perform display, and an operation panel having a plurality of operation switches and substantially transmitting light through at least a portion thereof which requires illumination. When the overall rear surfaces of the display panel and the liquid crystal display panel are adhered to the electroluminescent panel by an adhesive, the vibration sound generated from the electroluminescent panel can be reduced. Further, when an appropriate pigment is diffused into the adhesive, light for illuminating the display panel and the operation panel is adjusted to a desired color.
