Abstract:
1. A display device, comprising: a group of first light emitting elements which includes a plurality of first light emitting elements arranged in a line from a first point to a second point in a first arrangement direction; a light emission control unit which is configured to display a display level to be indicated by causing light emission of a first given number of the first light emitting elements, which corresponds to the display level, that starts with the first point and ends with a third point among the plurality of first light emitting elements, wherein the third point indicates the second point or a point existing between the first point and the second point in the first arrangement direction; and a group of second light emitting elements which includes a plurality of second light emitting elements arranged in parallel with the group of first light emitting elements from a fifth point to a sixth point in a second arrangement direction, which is a direction different from the first arrangement direction, and emits light of a color that is different from that of the first light emitting elements, wherein the display device further comprises a diffusion plate which is arranged at a front side of the group of first light emitting elements, the light emission control unit is configured to control light emission of a second given number of the first light emitting elements starting from a fourth point to the third point among the first given number of the first light emitting elements, with decreasing brightness towards the third point, the fourth point indicates the first point or a point existing between the first point and the third point in the first arrangement direction, and the light emission control unit is configured to cause light emission of a third given number of the second light emitting elements that starts with the sixth point and ends with a seventh point among the plurality of second light emitting elements, wherein the seventh point indicates a point arranged at a position overlapped with the fourth point in the second given number of the first light emitting elements, and also to control light emission of a fourth given number of the second light emitting elements starting from the seventh point to an eighth point among the third given number of the second light emitting elements, with decreasing brightness towards the seventh point, wherein the eighth point indicates the sixth point or a point existing between the sixth point and the seventh point in the second arrangement direction.
