  • Patent number: 7903198
    Abstract: The present invention relate to a liquid crystal display device using a light emitting diode (LED) module as a light source for backlight. Storing portions (21a-21e) are provided at positions facing a light emitting diode modules (25) on a light guide plate (21) constituting the backlight, and the light emitting diode modules (25) are inserted into the storing portions (21a-21e). Furthermore, under a status where an insulating substrate (26) mounted with the light emitting diode modules (25) is held by a holding plate (28), the holding plate (28) is removably attached to a heat sink substrate (27). The backlight has a structure wherein the light emitting diode module (25) can be replaced. Furthermore, since heat generated at the light emitting diode module (25) can be efficiently dissipated to the heat sink substrate (27), temperature increase of the light emitting diode module (25) is suppressed, and lifetime can be lengthened, and deterioration of luminous efficiency can be prevented.

  • Publication number: 20080057297
    Abstract: An optical functional layer is formed on a first surface of a base material formed of polyester biaxially stretched. A protective material is formed on a second surface of the base material. The protective material includes fine particles, a lubricant, and a binder. The fine particles are formed of organic compound or inorganic compound. The binder is a polymer having a glass transition temperature of 40° C. or more. The lubricating properties of the surface are improved by the lubricant. As the lubricating properties improve, a necessary additional amount of the fine particles becomes less. Thereby, it is possible to prevent the degree of transparency from decreasing. Accordingly, the multi-layer sheet having high degree of transparency and excellent resistance to flaws can be obtained. It is possible to reduce bright unevenness by using the multi-layer sheet as the diffusion sheet.
