Abstract: This invention was made to reduce cost and the number of assembly processes and improve productivity by making viewing angle characteristics of light emitted from a light emitting surface even irrespective of a point in a bar-shaped light guide. A bar-shaped light guide of this invention comprises a light incident surface for receiving light emitted from a point light source, a light emitting surface, which is orthogonal to the light incident surface, for emitting light received on the light incident surface in a form of beam light, and a pattern surface made up of a side of the light incident surface and a side of the light emitting surface and having a plurality of grooves formed thereon. The plurality of grooves are regularly arranged on the pattern surface. An angle formed by the groove 106 and the side of the light emitting surface on a side of the point light source is 35-55°.

Abstract: In a beam irradiation device of the present invention, laser beams emitted from a semiconductor laser impinge on an irradiation lens supported by a lens actuator. The laser beams that have passed through the irradiation lens change in outgoing angle in the direction of a y-z plane as the lens actuator is driven. A laser beam scan in the target region is thus performed. A part of the laser beams that have passed through the irradiation lens is reflected and separated by a beam splitter. The separated beams are converged on a PSD through a converging lens. A DSP control circuit monitors a scan position of the laser beams that have passed through the irradiation lens based on a signal from the PSD. When an irradiation position has deviated from a scan trajectory, the DSP control circuit controls an actuator driving circuit to draw the irradiation position back onto the scan trajectory. This beam irradiation device can realize a smooth and stable beam scan operation with a simple construction.

Abstract: A display device includes a light guide plate. A light incident on the light guide plate from a linear light source is reflected by a reflecting surface of each of prisms and emitted from a lower surface of the light guide plate. The emitted light is irradiated onto a liquid crystal panel, reflected by a reflecting layer provided within the liquid crystal panel and advances toward a front direction of a screen. Herein, the light guide plate has on its lower surface as an emission surface a number of minute protrusions each having a shape of triangle in vertical cross-section in a manner that the protrusions cover with no space therebetween a whole effective area of the lower surface, and thereby to obtain an antireflection effect.

Abstract: A light guide plate is provided including a first lens portion comprising a plurality of recessed or projected lenticular unit lenses formed of the same resin as that of the light guide plate on a light emission surface. The plurality of lenticular unit lenses in the first lens portion are triangular prism portions whose respective vertexes have an angle of 125.degree. to 165.degree. and are so arranged that their respective ridge lines are nearly parallel to each other. Such construction makes it possible to set the number of lenticular lens sheets used to one or to further eliminate the necessity of the lenticular lens sheets, so that the cost of parts and the fabrication cost of the light guide plate can be reduced. A second lens portion may be provided on a light reflective surface opposite to the light emission surface on which the first lens portion is disposed, the second lens portion including a plurality of recessed or projected lenticular unit lenses formed of the same resin as that of the light guide plate. Alternatively, a light guide plate is provided having a plurality of grooves with approximately equal groove widths formed on a surface opposite to a light emission surface, the grooves being arranged substantially parallel to each other and the spacing between the grooves narrowing as the distance from the light incident surface increases, with the spacing from the far end of one of the plurality of grooves proximate to the light incident surface to the near end of a groove adjacent thereto farther away from the light incident surface being 5 to 15 times the groove width.
