LIGHT GUIDE PLATE, AND PLANAR LIGHTING DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE USING SUCH LIGHT GUIDE PLATE |
摘要 |
<p>A parallel groove of a light guide place for accommodating a light source has, in a perpendicular cross section, a shape composed of a pair of contour lines that approach each other toward a light emitting plane, cross at a peak, and has a part where an inclination angle to a line vertical to the light emitting plane changes, and the inclination angle at a base end side far from the peak is sharper than that at a tip end side close to the peak. Thus, uniform and high brightness light can be emitted.</p> |
