Abstract: To provide a illuminating device that is of small size, light weight and that has lower production costs for illuminating a reflective type liquid crystal display device that performs high contrast, moreover high definition and high-quality image display, thereby enabling realization of an image display that is of small size and light weight and that can be produced at low-cost. The display device comprises a light source 5 disposed in a lateral position in relation to the image display surface 3 of the reflective type liquid crystal display device 2, that emits linearly polarized light, and a plurality of reflecting members 6 disposed to the front of the image display surface 3 and separated from the image display surface 3, that reflect light emitted from the light source 5 and inject this light substantially perpendicularly in relation to the image display surface 3.

Abstract: A light deflection element has a pair of oscillating elements (6) and (7) having arms (6a) and (6b), and (7a) and (7b). respectively, the outer ends of which are fixed to a pair of supports (3) and (4) of a base (2), and the inner ends of which are free ends, a reflective mirror (8) disposed between arms (6a) and (6b), and arms (7a) and (7b) of the pair of oscillating elements (6) and (7), pairs of torsion springs (9a and 9b) and torsion springs (10a) and (10b), linking the inner ends of the arms (6a) and (6b) and the inner ends of the arms (7a) and (7b), respectively, at a pair of positions that are symmetrical about an axis (L) that passes through the center of gravity of the reflective mirror, and a drive apparatus (D) for applying a drive force separately and independently to the oscillating elements (6) and (7), so as to move the inner ends of the arms (6a), (6b), (7a), and (7b) upward and downward separately and independently.

Abstract: A thin film magnetic head 10 is comprised of a lower core 1b, a magnetic gap 2, a coil 4, an upper core 1a, a protective substrate 6, a first inorganic insulation film 3 and a substrate 7 on which the lower core, the magnetic gap, the coil, and the upper core are provided. The protective substrate is welded to the substrate by using a welding glass 5. A second inorganic insulation film 3b is additionally provided on the substrate so that the substrate is sandwitched between the first and second inorganic insulation films to prevent the substrate from warping when heated for welding.
