摘要： PROBLEM TO BE SOLVED: To provide a grating element and a manufacturing method thereof, using a high molecular liquid crystal by a simple and easy process, wherein the flexibility of the element constitution is improved by stabilizing the alignment of the liquid crystal without depending on an alignment layer requiring high temperature treatment. SOLUTION: Because the liquid crystal molecules are spontaneously aligned along the longitudinal direction of a groove by filling a groove part of a mold having prescribed recessed and projecting parts, with a polymerizable liquid crystal to cause molecule mutual action between the groove surface and the liquid crystal, the polarizing diffraction grating 2 is structured to align the liquid crystal in the groove longitudinal direction without particularly applying alignment treatment on the surface of the substrate, and a separation element having optical anisotropy is stably formed when the polymerizable liquid crystal is cured by the light irradiation in this state. The formed high molecular liquid crystal grating 2 is next peeled off and transferred on a resin sheet 1 through an adhesive layer 4 composed of a photocurable liquid resin and non-polarized light diffraction grating 3 comprising the photocurable resin is formed in a surface thereof using such a mold having preliminarily formed prescribed projecting and recessed parts.

摘要： PROBLEM TO BE SOLVED: To provide an illumination apparatus which can condense light emitted from a light source at a high efficiency and can obtain a high front surface luminance.
SOLUTION: An optical adjustment member 1 in a backlight 50 is provided with prism sheets 2 and 3. A prism 21 inside the prism sheet 2 is in parallel with a prism 31 inside the prism sheet 3. Moreover, a side surface 211 of the prism 21 and a side surface 311 of the prism 31 are formed so that a luminance peak beam emitted from a light guide plate 102 at a predetermined angle AO can enter at less than a critical angle. An emitted light from the light guide plate 102 is dispersed in a range of a predetermined angle with the predetermined angle AO as a luminance peak, but since it is collimated gradually by the prisms 21 and 31, a ratio of beam composition entering into the side surfaces 211 and 311 exceeding the critical angle out of the emitted light can be controlled. As a result, a ratio of a total reflected light at the side surfaces 211 and 311 can be controlled and a light loss can be controlled.
