摘要： A lighting device comprises a light guide plate having a light incident surface and a light exit surface, at least one point light source for emitting light that is incident on the light incident surface of the light guide plate and is guided by the light guide plate to the light exit surface of the light guide plate, and micro-structures disposed on a surface of the light guide plate that is opposite to the light exit surface thereof for scattering light from the point light source that is incident on the light incident surface. A longitudinal direction of each of the micro-structures is substantially aligned with a direction in which the light from the point light source is incident on each of the micro-structures. Each of the micro-structures has an inclined surface for reflecting the incident light toward the light exit surface of the light guide plate. A base line of the inclined surface of each micro-structure is disposed substantially orthogonal with the direction in which the light from the point light source is incident on each of the micro-structures.

摘要： A lighting device includes a light guide plate and a point light source located on a light incident surface side of the light guide plate. Micro-structures for light-scattering are provided separate from one another on a surface opposed to the light exit surface of the light guide plate. Each of the micro-structures for light-scattering has an orientation in a longitudinal direction. The longitudinal direction becomes substantially parallel to a direction joining the micro-structure for light-scattering with the point light source. With this structure, a high intensity of the lighting device is realized. The surface opposed to the light exit surface of the light guide plate is divided into a plurality of regions. A thickness of the light guide plate reduces stepwise in the respective regions as a distance from the point light source increases.

摘要： The invention realizes a phosphor film that has a fluorescent characteristic excellent in resistance to humidity and provides, using the phosphor film, a liquid crystal display device that is excellent in resistance to humidity and has satisfactory calorimetric property and color mixture property. Phosphor particles that are excited by incident light and emit light having a wavelength different from the incident light are mixed in a binder. The binder mixed with the phosphor particles is sandwiched between a translucent film and a non-permeable layer as a phosphor layer to form a phosphor film. This phosphor film is provided at least in one place among a place between a light source and a light guide of a lighting device, a place on a light irradiation surface of the light guide, and a place between the light guide and a reflection plate. Moreover, the phosphor particles have a characteristic that a wavelength absorbed by a color filter of a display element is set as an excitation wavelength and a luminescent wavelength is in a region transmitted by the color filter. With this phosphor film, it is possible to realize a display device that has extremely high luminance efficiency and color reproducibility.
