Abstract:
Provided is a display device in which design properties have been improved by eliminating the flickering when the display level changes. A microcomputer (5) causes light emission of first LEDs (23 and 24) which are the first and second ones counting from the right end among the emitting first LEDs (21 to 24), with decreasing brightness towards the right end. Furthermore, the microcomputer (5) causes light emission of second LEDs from a second LED (77) which is disposed at the right end of the second LEDs (71 to 77), to a second LED (73) which is disposed at a position overlapped with the first LEDs (23 and 24) that emit light with decreasing brightness towards the right end, and also causes light emission of second LEDs (73 and 74), which are the first and second ones counting from the left end among the emitting second LEDs (73 to 77), with decreasing brightness towards the left end.
