Frame) under the color that can be shown on the display surface of display device be blue (B) and green (G).In contrast, in pinkish red colour field
The color that can be shown on the display surface of display device under (1/2 frame) is blue (B) and red (R).
As known to Fig. 3 B, blue (B) though for cyan field, pinkish red colour field which can show.With this phase
Instead, green (G) can only show that red (R) can only be shown in magenta off field off field in cyan.As a result, blue (B)
Output level (luminous intensity) has the trend than green (G), red (R) enhancing.
In order to solve this imbalance, in the present apparatus, such as shown in Fig. 3 A and Fig. 3 C, reach out for blue (B),

Luminous intensity may not be equal.In order to obtain the position of the white on chromatic diagram, preferably in the characteristic (transmitance for considering each colour filter
Deng) blue (B), green (G), the luminous intensity of red (R) are reset later.
Although above-mentioned one frame of embodiment includes two cyan field, pinkish red colour field fields, it is not limited to this.
In Fig. 4 A, Fig. 4 B and Fig. 4 C, being shown as a frame includes three cyan field, pinkish red colour field and white field fields.
Therefore, as shown in Figure 4 A, it is cyan, white and magenta that the multiple Light-emitting diode LED for constituting lighting device, which include illuminant colour,
The light emitting diode of color.
In addition, the light source unit LU shown in Fig. 3 A and Fig. 4 A, with multiple Light-emitting diode LED is configured in and leads
The end surface side of the first direction X of tabula rasa.But the allocation position of light source unit LU is not limited.Light source unit LU can also
To be configured at the end face of the second direction Y of light guide plate.Light source unit LU shown in Fig. 4 A be capable of providing cyan field, white field with
And pinkish red colour field.In Figure 4 A, though it is shown that the light emitting diode of white, but light source unit LU may not have to have white
Light emitting diode.This is because white field can be by lighting cyan simultaneously as Fig. 9 A described later, Fig. 9 B
It is provided with the light emitting diode of magenta.
Fig. 4 B is divided into the timing of cyan field, white field and pinkish red colour field during showing a frame.Moreover, showing
The cyan of illuminant colour as lighting device, the field of white and magenta and the relationship of the color for the light being emitted from colour filter.
Lighting device has cyan field (1/3 frame), white field (1/3 frame) and pinkish red colour field (1/3 frame) during a frame.In cyan
The color that can be shown on the display surface of display device under field (1/3 frame) is blue (B) and green (G).At white field (1/3 frame)
Under the color that can be shown on the display surface of display device be blue (B), it is green (G) and red (R), at this point, result can be shown
Show white (W).The color that can be shown on the display surface of display device under pinkish red colour field (1/3 frame) is blue (B) and red
(R)。
Fig. 4 C show it is in during a frame shown in Fig. 3 C, increase again on the basis of cyan field, pinkish red colour field
The situation of the light emitting diode of white (W=R, G, B).In the present embodiment, since a frame has been divided into three fields, thus
The switching frequency of lighting device increases compared with a case where frame of pervious embodiment has been divided into two fields.But
It is the field of the field R, G, B and W four with W existing apparatus, compared with existing device, present embodiment
Situation lacks a field.Therefore, even if increasing W, the power consumption of present embodiment will not increase as existing device.
