摘要： To increase an amount of the light that can be used for the display efficiently in the total amount of the emitted light in the liquid crystal display device having the surface lighting device such as the front-light. The light (a) becomes the light component of the linearly polarized light by passing the retardation plate (11a). In the reflective polarizer (11b), only the light (b) that is a component of the polarization axis of the reflective polarizer (11b) passes through the reflective polarizer (11b) to enter into the end portion of the light guide (12). The light that is a component other than the component of the polarization axis of the reflective polarizer (11b) is reflected on the reflective polarizer (11b). The light reflected on the reflective polarizer (11b) changes from the linearly polarized light to the circularly polarized light by passing through the retardation plate (11a). The circularly polarized light (d) is transmitted into the light stick (10) and is reflected on the reflective film in the light stick (10). The reflected light (e) change from the circularly polarized light to the linearly polarized light by the retardation plate (11a). The linearly polarized light (f) passes through the polarization axis of the reflective polarizer (11b) to enter into the end portion of the light guide (12).

摘要： An object of the invention is to provide a surface illumination device and a display device using it, which can contribute to improvement of display qualities. A surface illumination device 10 comprising a light guide plate 1 for propagating incident light inside itself and reflecting the light at the reflecting prism face 1S to output the light from the light exit face. This further comprises: a polarizing plate 3 provided on the light exit face; and an anti-reflection film 4 provided on the polarizing plate 3. The reflecting prism face 1S extends so that a direction of electric vector's vibration of an s-polarized light component of a reflecting light ray caused by an incident light ray in a predetermined propagation direction is in parallel with a polarization axis of the polarizing plate 3, whereby a light efficiency can be improved.

摘要： The color gamut of a image display device is improved by the introduction of a broad band stop filter in combination with a band pass filter, a first light field and a second light field. The first light field is generated by a first and a second light source, emitting blue and green light, respectively. The second light field is generated by said second light source and a third light source emitting red light. The color gamut is improved since the band pass filter facilitates a displacement of the color point of said second light source towards shorter wavelengths, as the band pass filter transmits some of the blue light in the first light field. Similarly, a displacement towards longer wavelengths is facilitated, as the filter transmits some of the red light of said second light field. Hence, four primary colors are generated by only three light sources.
摘要翻译：通过与带通滤波器，第一光场和第二光场的组合引入宽带阻带滤波器来改善图像显示装置的色域。第一光场由第一和第二光源产生，分别发射蓝光和绿光。第二光场由所述第二光源和发射红光的第三光源产生。由于带通滤波器有助于使第二光源的色点朝向较短波长的位移，因为带通滤光器透射第一光场中的一些蓝光，所以色域得到改善。类似地，随着滤光器透射所述第二光场的一些红光，便于朝较长波长的位移。因此，只有三个光源产生四原色。
