摘要： PROBLEM TO BE SOLVED: To obtain a display device with good display visibility as well as to realize a small-size and lightweight device. SOLUTION: This device is equipped with a reflection type liquid crystal panel 1 and an illumination plate 2 for a front light, and the illumination plate 2 for the front light consists of a light guiding layer 6 consisting of a transparent plate having projected ribs 5 and a protective layer 7 which consists of a material having a lower refractive index than the material of the light transmission layer 6 and which is tightly laminated on the light guiding layer 6. Thus, it is not necessary to form an air layer which is conventionally formed to satisfy the conditions for total reflection, and specified strength and good display visibility can be obtd. while the illumination plate 2 for the front light is made smaller in size and lightweight by a simple structure.

摘要： PROBLEM TO BE SOLVED: To obtain a liquid crystal panel or driver or liquid crystal display device which lessens screen unevenness and optical defect and further to provide a process for production and laser annealing device suitable for embodying these devices. SOLUTION: The intensity distribution of a laser beam emitted from a laser oscillator 14 is made uniform by using a Fourier transform type phase hologram 11. A substrate 13 is scanned while the position of this laser beam cast onto a substrate 13 is oscillated in a direction orthogonal with the beam scanning direction by a mirror 16 of a ganlvanoscanner, by which the points to be formed with the polysilicon thin-film transistors(TFTs) on the substrate 13 are laser annealed and the TFTs suppressed in the variation of the mobility or threshold voltage within ±10% are formed.

摘要： PROBLEM TO BE SOLVED: To miniaturize an optical head and to reduce its price by obliquely cutting a light emission part toward an optical disk of a light propagation path where light is propagated in a zigzag between upper and lower surfaces and polarizing the zigzag light and emitting it in vertical direction onto the upper and lower surfaces of a substrate. SOLUTION: A substrate 1 consists of optical plastic that is 1.2 mm in thickness, 2 mm in width, and 3 mm in length. Light being emitted in vertical direction from a semiconductor laser 4 with a wavelength of 0.79 nm is refracted, for example, at 12.5 degrees in the substrate 1 on an oblique surface 8a that is an incidence surface being cut obliquely. With light being split into three beams by a position signal detection optical means 9 consisting of a diffraction grating, o-order reflection light enters a condensing means 3 via a beam splitter 7. The condensing means 3 consists of a Fresnel lens and emits light being reflected once by a reflection layer 6b on a lower surface vertically via an oblique surface 8b being cut on an upper surface for focusing on a disk 10. The reflected light is directed toward a photo detector 5 after it becomes primary diffraction light by the beam splitter 7.
