This invention relates to a display apparatus, comprised of: a display portion 11 consisting of a plurality of light-emitting elements (11a) equipped on a substrate so as to form a display region in a predetermined shape; a drive portion (12) that makes each light-emitting element illuminate; a control portion (13) that controls the drive portion; a power supply portion (16) that supplies electric power to the drive portion and the control portion; and a switch portion (17) with the function of turning on and off the power from the power supply portion to the drive portion, and to the control portion, based on operation instructions: having a semi-translucent cover (11c) of ample size to encompass the entire display region of the display portion; having the light-emitting elements of the display portion arranged in such a way that the light can be brightened gradually from one end of the display region toward the other end thereof, either by the increasing intensity of light emission or by the increasing density of the light-emitting elements thereof; and thereby the control portion puts the drive portion under control to make the light-emitting elements illuminate one after another from one end of the display region to the other end thereof repeatedly in a predetermined time interval. <IMAGE> |
