In addition, the length of a base portion of each prism is large such that a resin is filled up to the apices of prisms. That is, in the light guiding plate according to the invention, each of the prisms is not constituted by only a gentle-sloped surface and a steep-sloped surface, but a flat surface is provided between gentle-sloped surface and the steep-sloped surface, and the angle between the steep-sloped surface and the flat surface is formed to be large.

The light guiding plate is provided with prism portions each having a slight inclined plane and a steep inclined plane arranged closer to one edge than the slight inclined plane. A plurality of light refracting portions each having a refractive surface and a reflective surface are provided on an incident surface of the prism sheet. Light introduced into the light guiding plate from the light source is emitted from the slight inclined plane and is then incident on the light refracting portion. The light is introduced into the prism sheet by the refracting surface and is then reflected from the reflective surface to be emitted.

摘要： A front light of the invention has a light guide plate, an intermediate light guide disposed along the side end surface, and a light emitting device disposed on an end surface thereof. The pitch between grooves having a wedge shape in cross section formed on a backside of the light guide on the opposite side of the light guide plate is formed so as to be linearly varied with respect to the distance from an end surface disposed with the light emitting device to the groove. The depth of the groove is formed more deeply as the grooves are positioned more apart from the end surface. In the distribution of the depth of the groove with respect to the distance from the end surface to the groove, there are a first area where the depth of the groove is linearly increased with respect to the distance from the end surface disposed with the light emitting device to the groove, and a second area formed apart from the light emitting device more than the first area in which the increasing rate of the depth of the groove with respect to the distance from the end surface is greater than that in the first area.

摘要： Disclosed is an illuminating unit capable of effectively introducing light emitted from a light source into a light guide sheet to improve the brightness of light and emitting uniform color light. Light emitted from a light emitting diode of a light source unit is incident on a side surface of a light guide sheet. A spacer aligns the emission center of the light emitting diode with the center of the light guide sheet in the thickness direction thereof. The incident light travels in the light guide sheet and is then diffused in light emitting regions provided on the main surface of the light guide sheet. Then, the diffused light is emitted to the outside. In addition, light components emitted from a gap between the light emitting diode and the side surface of the light guide sheet or light components emitted from the upper surface of the light source unit to the outside are reflected to the light guide sheet by a cover member.
