    • Provided is a planar illuminating device having light source section (1) emitting linearly polarized laser light and having a light guide (12) with a rectangular parallelepiped shape having one main surface with a mirror array (12c) thereon. The mirror array (12c) has a plurality of reflecting surfaces totally reflecting laser light incident on an incident surface (12a), of the light guide, perpendicular to the one main surface and emits the laser light from an emitting surface (12b), of the light guide, perpendicular to the one main surface, wherein the reflecting surfaces are formed in a stepped manner. Further, the planar illuminating device includes a light-guiding plate (3) making the laser light, emitted from the light guide (12), incident on an incident surface (3a) of the light-guiding plate and emitting the laser light from an emitting surface (3b) of the light-guiding plate.
    • 本发明提供一种平面照明装置,其具有发射线偏振激光的光源部分(1),并且具有具有一个主表面的具有矩形平行六面体形状的导光体(12),其上具有反射镜阵列(12c)。 反射镜阵列(12c)具有多个反射表面,其全部反射入射到入射表面(12a)上的激光,垂直于一个主表面并从发射表面(12b)发射激光 所述导光体垂直于所述一个主表面,其中所述反射表面以阶梯形式形成。 此外,平面照明装置包括导光板(3),其使从光导(12)发射的激光入射在导光板的入射面(3a)上并从 导光板的发光面(3b)。

    • A surface illumination apparatus includes: a light source; an end-surface light-guide portion which guides light emitted from the light source in a long-side direction thereof and generates emitted light in a short-side direction thereof; and a light guide plate which allows the emitted light to be incident upon an end-surface portion thereof and emits the incident light from one main-surface portion thereof. The end-surface light-guide portion includes a plurality of polarization control portions arranged in the long-side direction; the plurality of polarization control portions each has a half-wave plate and a polarizing prism; the end-surface light-guide portion emits the emitted light in the form of either of S-polarized light and P-polarized light, using the plurality of polarization control portions; and the light guide plate emits, as output light, either of S-polarized light and P-polarized light from the one main-surface portion.
