Abstract
According to one embodiment, a display device, includes a display panel having a light transmission property, the display panel includes a first sub-pixel exhibiting a first color, a second sub-pixel exhibiting a second color, a third sub-pixel exhibiting a third color, a dummy pixel exhibiting a fourth color having brightness lower than the first to third colors, and a light modulating layer capable of changing a light transmission property and a light scattering property of regions corresponding to the first to third sub-pixels and the dummy pixel, respectively.

A method of driving a display device,
- the display device comprising:
- a first sub-pixel exhibiting a first color;
- a second sub-pixel exhibiting a second color;
- a third sub-pixel exhibiting a third color;
- a first substrate having a light transmission property;
- a second substrate opposed to the first substrate and having a light transmission property;
- a first color filter disposed on the first sub-pixel of the second substrate to allow light of the first color to be transmitted;
- a second color filter disposed on the second sub-pixel of the second substrate to allow light of the second color to be transmitted;
- a third color filter disposed on the third sub-pixel of the second substrate to allow light of the third color to be transmitted;
- a light modulating layer located between the first substrate and the second substrate and capable of modulating a transmission mode indicating a light transmission property and a scattering mode indicating a light scattering property;
- and
- a light source unit illuminating the light modulating layer, emitting light of the first color in a first field for driving the first sub-pixel, emitting light of the second color in a second field for driving the second sub-pixel, and emitting light of the third color in a third field for driving the third sub-pixel,
- the method comprising:
- urging the light of the first color to be emitted from the light source unit, in the first field, and urging the light of the first color to be absorbed into the second and third color filters and the light of the first color to be emitted from the first substrate by setting at least one of the second and third sub-pixels in the scattering mode.
