Abstract
A backlight device includes a light guide plate including a first incident surface, and one or more second incident surfaces that are connected to the first incident surface and inclined with respect to the first incident surface in a top plan view; at least one green illuminant arranged to face one of (i) the first incident surface and (ii) the one or more second incident surfaces; and at least one red illuminant arranged to face the other of (i) the first incident surface and (ii) the one or more second incident surfaces. At least one of (i) the green light emitted from the green illuminant, and (ii) the red light emitted from the red illuminant, contains a blue component whose emission peak wavelength is 420 nm to 500 nm.
Claims20
A backlight device comprising:
- a light guide plate including:
- a top light emitting surface,
- a lateral first incident surface, and
- one or more lateral second incident surfaces,
- wherein the one or more second incident surfaces are connected to the first incident surface and inclined with respect to the first incident surface in a top plan view;
- at least one green illuminant arranged to face one of (i) the first incident surface and (ii) the one or more second incident surfaces, the at least one green illuminant being configured to emit a green light toward said one of (i) the first incident surface and (ii) the one or more second incident surfaces;
- and
- at least one red illuminant arranged to face the other of (i) the first incident surface and (ii) the one or more second incident surfaces, the at last one red illuminant being configured to emit a red light toward said other of (i) the first incident surface and (ii) the one or more second incident surfaces,
- wherein at least one of (i) the green light emitted from the green illuminant, and (ii) the red light emitted from the red illuminant, contains a blue component whose emission peak wavelength is 420 nm to 500 nm.

- wherein the one or more second incident surfaces are connected to the first incident surface and inclined with respect to the first incident surface in a top plan view;
- at least one first illuminant arranged to face the first incident surface, and configured to emit a first light toward the first incident surface;
- and
- at least one second illuminant arranged to face the one or more second incident surfaces, and configured to emit a second light that is different from the first light toward the one or more second incident surfaces.
