Front view of the guide member.

The light source 30 includes a light emitting diode (LED) 30a. Multiple LEDs may be provided at equal intervals and may be provided to form a module. Each module may be provided at the edge portion of the light guide plate 40 . The LEDs include blue LEDs. The light source 30 may also include a circuit board 30b, and the circuit board 30b may be provided to send electrical signals to the LEDs 30a and turn on/off the LEDs 30a. As an exemplary embodiment, the LEDs 30a are provided in a row on the circuit board 30b and operate. The light sources 30 are provided on both sides of the space between the light guide plate 40 and the inner surface of the bottom chassis 84 , that is, on the sides of the side surface portion 84 b of the bottom chassis 84 . Therefore, the light generated by the light source 30 is emitted to the rear surface portion of the bottom chassis 84 through the space between the rear surface portion of the bottom chassis 84 and the light guide plate 40 .

The light guide plate 40 may include a reflection part 45 on a rear surface thereof. Specifically, the light guide plate 40 may include a light guide part 40 a and a reflection part 45 . The reflection part 45 may be provided at the rear surface of the light guide plate 40 so that the light generated by the light source faces the forward direction.

The optical sheet 60 is interposed between the light guide plate 40 and the display panel, and changes the optical characteristics of light emitted by the light guide plate 40 .

The QD sheet 50 is provided for color reproducibility. The color reproduction factor is a measure of how close a color is to a natural color and how large an area can be marked on color coordinates. Since the QD sheet 50 has higher color purity of white light than conventional technology, which employs color filters to convert white light emitted by LEDs, the efficiency of light passing through the color filters becomes higher, and the power efficiency of the entire display increases. The QD sheet 50 may also be referred to as a quantum dot sheet.

QDs will now be described. Generally, electrons present in the valence band jump to the conduction band when the electron absorbs energy. After that, the electron loses energy and returns to the valence band, at which point the absorbed energy is radiated as light. QDs produce strong fluorescence in narrow wavelength bands. Visible light of all kinds of colors can be generated depending on the size of the QDs. In addition, since QDs themselves produce natural colors, there is no color loss, so QDs are also materials with high color reproducibility. When the particles of the QDs are smaller, light with shorter wavelengths is generated, and when the particles are larger, light with longer wavelengths is generated. The QDs may be compounds such as cadmium selenide (CdSe), cadmium sulfide (CdS), cadmium telluride (CdTe), zinc selenide (ZnSe), zinc telluride (ZnTe), zinc sulfide (ZnS), and the like.

The QD sheet 50 may be provided such that light passing through the light guide plate 40 is emitted through the QD sheet 50 . The QD sheet 50 may be attached to the light guide plate 40 at the front surface of the light guide plate 40 . The QD sheet 50 is attached to the front surface of the light guide plate 40 so that light emitted from the light guide plate 40 passes therethrough.

Since the light of the LED passes through the light guide plate 40 to the QD sheet 50, the QD sheet 50 is less affected by the heat of the LED, so it is more reliable.

The QD slices 50 may include yellow QD slices 50 corresponding to blue LEDs. The blue light emitted by the blue LEDs is converted into white light when passing through the yellow QD sheet 50 .

As described above, the light guide plate 40 according to an exemplary embodiment may include the light guide part 40 a and the reflection part 45 . Here, the reflection portion 45 may also be formed as a separate sheet.

In an exemplary embodiment, the cross-section of the first guide part 110 is formed in a rectangular shape, and the cross-sectional area thereof may gradually increase. In such a configuration, the light guide plate groove portion 43 of the light guide plate 40 to be described later is seated on the first seat portion 114 through the first position guide portion 112 .
