Abstract:
A display device for a vehicle includes a liquid crystal panel (10), a light source (40), and a controlling means (50). The liquid crystal panel includes a particular display pixel (72) and a normal display pixel (62). The controlling means controls the ratio of the gradation value of the normal display pixel to a set gradation value of the normal display pixel as a gradation ratio of the normal display pixel. At the same time, it controls the ratio of the gradation value of the particular display pixel to a set gradation value of the particular display pixel as a gradation ratio of the particular display pixel. Further, the controlling means sets first and second modes as a control mode, the first mode in which the light source emits light, and the second mode in which the light source emits light with brightness lower than in the first mode. In the first mode, the controlling means sets the gradation ratio of the normal display pixel and the gradation ratio of the particular display pixel at a particular time to a maximum ratio. In the second mode, the controlling means executes a gradation processing for making the gradation ratio of the particular display pixel at a particular time higher than the gradation ratio of the normal display pixel.
