As in 1 shown can be a display arrangement 1 a light source 10 included to light 11 to radiate a color transformation element 20 include to a color of a part 12 of the light that comes from the light source 10 is emitted, and a light guide plate 30 include to receive light coming from the light source 10 is emitted by at least one surface.

The light source 10 can emit white light or predetermined colored light to the outside. The light source 10 may be one of various types of lighting devices capable of emitting light. For example, the light source 10 a cold cathode fluorescent lamp (CCFL) or a light emitting diode (LED). However, the light source can 10 one of several types of lighting devices that may be considered by one of ordinary skill in the art.

Light coming from the light source 10 may be emitted to the color transformation element 20 or the light guide plate 30 be transmitted.

All or part of the light coming from the light source 10 can be emitted to the light guide plate 30 be transferred and then into the interior 32 the light guide plate 30 reach. In this case, light can be emitted from the light source 10 is broadcast in the interior 32 the light guide plate 30 through a surface of the lightguide plate 30 reach. The light that goes into the interior 32 the light guide plate 30 Occurs, one or more times in the interior 32 the light guide plate 30 can be reflected and then emitted in a direction opposite to the light source 10 is. All or part (for example, a and b) of the light in the interior 32 the light guide plate 30 is reflected, can be uniform to some extent from the top surface 33 the light guide plate 32 be emitted to the outside.

Alternatively, the upper housing 101 in the middle case 130 be integrated.

4 briefly illustrates the display device according to an embodiment of the present disclosure, and 5 FIG. 12 shows an example of directions in which emitted light is incident to the display device according to the first embodiment of the present disclosure. FIG.

Referring to 4 , light can be from the light source 180 is emitted through the light guide plate 160 , the quantum dot plate 140 , the optical disk 120 and the display panel 110 run, and then emitted as a given mask to the outside.

Referring to 5 can the optical disk 120 on the first attachment part 131 and the quantum dot plate 140 be arranged. Because in this case the first attachment part 131 on the quantum dot plate 140 is arranged to the quantum dot plate 140 to fix, can the quantum dot plate 140 be arranged to be lower than the first attachment part 131 to be closer to the PCB 181 as the first attachment part 131 to be. Accordingly, an area 120a the optical disk 120 which is the quantum dot plate 140 touched, be located lower than another area 120b the optical disk 120 , the first attachment part 131 touched, that is closer to the PCB 181 be arranged as the other surface 120b the optical disk 120 , Due to the difference in position, the optical disk can 120 a bent part 120c exhibit as shown in a circle. In this case, the optical disk 120 be bent in an almost "S" shape, as in 5 will be shown. Accordingly, an air gap 120d between the bent part 120c the optical disk 120 , the first attachment part 150 and the quantum dot plate 140 be formed. The air gap 120d can be much larger than a gap between the optical disk 120 and the quantum dot plate 140 be.

If it is not a color transformation element 150 There may be some of the light coming from the light source 180 is radiated from the lower surface of the first attachment part 150 be reflected on the quantum dot plate 140 or the light guide plate 160 come in, from the reflector 170 be reflected, then through the air gap 120d go, and to the optical disk 120 and the display panel 110 be transferred (route A). In this case, the light passing through the air gap 120d is directed, again in the air gap 120d reflected as in the gap between the optical disk 120 and the quantum dot plate 140 , However, since the air gap 120d is greater than the gap between the optical disk 120 and the quantum dot plate 140 can the light with the quantum dot plate 140 react in a relatively weak degree, and as a result, the light passing through the air gap 120d goes and then is issued to the outside, be different to incident light. For example, if the light source 180 blue light can emit light that passes through the air gap 120d is guided and then issued to the outside will be bluer than an intended color. Because the air gap 120d mainly in the edge of the light guide plate 160 or the quantum dot plate 140 is formed, which is adjacent to the light source 180 is as shown in 4 , may be in a peripheral area z, which is adjacent to the light source 180 is an image that may be bluer than an intended color.

The color transformation element 150 can change a color of the light that passes through the air gap 120d can go to prevent light of a color other than the intended color from escaping. When the light source 180 blue light emits, the color transformation element can 150 Emit light of a color that corresponds to the blue light. In this case, the emitted light may be yellow-enhanced light.

6 Fig. 13 is a view for describing a change in the color of light by the color transformation element 150 , More specifically shows 6 shows the CIE 1931 as defined by the International Commission on Illumination (ICI). In the CIE 1931 , as in 6 As shown, a green (G) color or greenish color may be mapped as the increase of the y-axis coordinates, and a red (R) color or reddish color may be mapped as the increase of the x-axis coordinate. Similarly, with zero approaching X and Y axis coordinates, a blue (B) color or bluish color may be imaged. Meanwhile, in the range between the green (G) color and the red (R) color, yellow (Y) color or yellowish color may be assigned.

When the light source 180 blue light emits, the blue light coming from the light source 180 is emitted, light of a color, the first point M out 6 equivalent. The color transformation element 150 can the blue light coming from the light source 180 is emitted, and corresponding to the first point M, to a color corresponding to a second point N in 6 corresponds, and can emit light of the converted color. In other words, the color transformation element 150 can emit yellow-enhanced light from the light emitted by the light source 180 is broadcast. Then, an intended color, or a color similar to the intended color, may be displayed instead of blue in the edge region z adjacent to the light source 180 is because yellow was amplified, even if the reaction of the color transformation element 150 leaking light with the quantum dot plate 140 is relatively weak. Accordingly, the color of the peripheral region z may be adjacent to the light source 180 in a display screen as a designated color.
