20100014025 | BACKLIGHT DEVICE, DISPLAY DEVICE, AND TELEVISION RECEIVER - A backlight device capable of preventing or reducing, even when an optical sheet bends, occurrence of luminance nonuniformity and/or shades due to the bend. The backlight device | 01-21-2010 |
20110007237 | LAMP HOLDER, BACKLIGHT DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - Disclosed is a lamp holding tool provided with lamp holding sections arranged in a same direction at fixed intervals, and flat-board like connecting sections whereupon the lamp holding sections are fixed. The lamp holding section has a shape which can abut to the lamp on different parts depending on relative angles to the lamp. As for the lamp holding sections, a distance between the lamps is changed by an angle formed by the arrangement direction of the lamp holding sections and the axis direction of the lamps. | 01-13-2011 |
20110014806 | LAMP CONNECTOR, BACKLIGHT DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - A valve holding portion including a pair of elastic deformation portions which is arranged opposite each other, whose gap is elastically opened and which sandwiches the valve and a feed portion that is coupled to at least one of the elastic deformation portions and that feeds electric power to the lead wire are included. The feed portion includes a lead contact portion formed such that, when the pair of elastic deformation portions holds the valve, comes into contact with the lead wire. | 01-20-2011 |

20160109637 | Light Source Device and Display Apparatus - Provided are a light source device which may disperse a force shifted in a plane direction due to a difference in thermal expansion by a reflection sheet so as to maintain good display quality, and a display apparatus using the light source device. The light source device includes a transparent plate used as a light guide plate, a light source disposed to face a part of a peripheral surface of the transparent plate along the part thereof, and a reflection sheet attached to one wide surface of the transparent plate, and the reflection sheet is provided with a plurality of cut lines formed in a prescribed range including a center thereof at a prescribed interval. Thereby, even if the transparent plate and the reflection sheet are thermally expanded in relation to the different expansion coefficients from each other, it is possible to prevent the reflection sheet from being peeled off from the transparent plate. | 04-21-2016 |
20160109643 | Light Source Device, Display Apparatus, and Method of Manufacturing Light Source Device - Provided are a light source device capable of uniformly illuminating, a display apparatus, and a method of manufacturing the light source device. Since a reflection sheet is adhered to a light guide plate through an adhesive layer, deflection thereof is suppressed. Since dot parts are filled in openings of an optical layer, it would be difficult for the dot parts to be distorted by an outer force. In addition, since the dot parts are formed by forming the optical layer and the adhesive layer in a large area in which an occurrence of distortion during forming is minimal, it would be difficult for the dot parts to be distorted during forming the same. Therefore, an occurrence of luminance unevenness caused by the deflection of the reflection sheet or the distortion of the dot parts may be suppressed. From the above result, it is possible to uniformly illuminate by the light source device. | 04-21-2016 |
