Abstract: A method for manufacturing soil-resistant glass the surface of which is covered with a coating film having a high hardness, and the soil-resistant glass are provided. A coating film comprising titania or/and titania-silica is formed by coating a glass surface with a photocatalyst solution comprising the titania or/and the titania-silica each having a photocatalytic function and heating the applied photocatalyst solution at a temperature higher than at least 100° C. The heating temperature may be a temperature higher than 100° C. and 300° C. or lower. The time of heating at the above-mentioned temperature may be at least 2 minutes or longer.

Abstract: According to one embodiment, an edge light-type back light unit includes, a light source, a light guide plate and a light quantity controller. The light source configured to exit light. The light guide plate includes a lens configured to prevent diffusion of the light exiting the light source and being incident onto a portion other than a portion corresponding to a vicinity of a boundary between the center portion and the periphery portion of the image display screen and a light diffuser of the light guide plate configured to diffuse light exiting the light source and being incident onto the portion corresponding to the vicinity of the border between the center portion and the periphery portion of the image display screen.

Abstract: According to one embodiment, an electric apparatus comprises a panel, a plurality of substrates at a back side of the panel, a plurality of first LEDs spaced apart from each other with gaps, on each of the substrates, and configured to illuminate the panel from the back side of the panel, and a plurality of second LEDs additionally arranged in the gaps at a substantially central portion in a lateral direction of the panel, of the gaps on each of the substrates, and configured to illuminate the panel from the back side of the panel.

Abstract: According to one embodiment, a backlight unit is of the edge light type that guides emitted light from a light source to a liquid crystal display panel by a light guide plate for irradiation from the back surface side thereof and includes a controller. The controller is configured so that the degree of irradiation at the center of a video display screen in the liquid crystal display panel is set to be greater than that at the periphery of the screen.

Abstract: According to one embodiment, a liquid crystal module includes a transmissive liquid crystal cell, a light source device, a light guide plate and a frame. The light source device includes a plurality of light-emitting elements arranged in a row on a board. The light guide plate includes a light incidence surface on which light emitted from the light source device enters and a light exit surface from which light that has entered the light guide plate through the light incidence surface is output. The frame is configured to hold a peripheral portion of the liquid crystal cell and the light source device and to comprise a first projection projecting from a position close to the light source device toward the light guide plate.

Abstract: A planar light source device comprises a light guide having a light entrance surface through which light enters, and a light exit surface, from which the light that entered through the light entrance surface exits, a light source disposed along the light entrance surface, and a reflecting body, which has two ends forming an opening to discharge the light emitted from the light source and sandwiching the light guide in a thickness direction, surrounds the light source, and reflects the light emitted from the light source toward the light entrance surface. The light exit surface has a grained surface region where a convex dot pattern is formed and a positioning region where no dot pattern is formed. One of the two ends of the reflecting body, which is brought into contact with the light exit surface, has an edge that is positioned in the positioning region.
