    Abstract: A display device includes a light source to emit light, a light guide plate on which the light emitted from the light source is incident and which irradiates light through a first and a second surface of the light guide plate, a quantum dot sheet on which the light irradiated through the first surface of the light guide plate is incident and which irradiates blue light, green light and red light, a reflective sheet for reflecting the irradiated light to the light guide plate, and a light-converting material at an edge portion of the light guide plate, the quantum dot sheet and the reflective sheet, for converting the light into a yellow light, green light or red light. The light incident on the quantum dot sheet includes the light emitted from the light source and the yellow light, the green light or the red light.

    Abstract: A light guide panel (LGP) for use in a liquid crystal display (LCD) apparatus includes a light-emitting pattern surface on which light-emitting patterns are formed, an opposite surface opposite to the light-emitting pattern surface, and four edge surfaces. Lenticular patterns are formed on one of the light-emitting pattern surface and the opposite surface. The light-emitting pattern surface includes a light-emitting part in which the light-emitting patterns are formed; and an edge part which extends along the four edge surfaces to enclose the light-emitting part and in which at least one fixing groove is formed to fix the LGP. The light-emitting part includes a pattern reducing region which faces the fixing groove and has a lower light-emitting pattern density than an other region of the light-emitting part.

    Abstract translation: 用于液晶显示（LCD）装置的导光板（LGP）包括其上形成有发光图案的发光图案表面，与发光图案表面相对的相对表面，以及四个边缘表面 。 透光图案形成在发光图案表面和相对表面之一上。 发光图案表面包括其中形成有发光图案的发光部分; 以及边缘部分，其沿着所述四个边缘表面延伸以包围所述发光部分，并且其中形成有至少一个固定槽以固定所述LGP。 发光部分包括面向固定槽的图案缩小区域，并且具有比发光部分的其它区域更低的发光图案密度。
