摘要:
A resin composition having a viscosity suitable for encapsulating optical devices such as light-emitting devices is provided. Specifically, the cured product of the resin composition has a refractive index greater than or equal to that of epoxy resins, exhibits excellent heat resistance and light resistance, and has thermal stress relaxation properties. The curable resin composition contains a fluorene group-containing acrylate or methacrylate represented by the following formula and a specific monofunctional acrylate or methacrylate: wherein X is —(CH2CH2O)n— or —(CH2CH2O)—CH2CH(OH)CH2O— with n being 1 to 5 and R is an acrylic or methacrylic group.

An electromagnetic wave suppression sheet (1) includes moisture-resistant films (11a), (11b) and an acrylate based polymer gel containing x wt % of an alcohol. The electromagnetic wave suppression sheet (1) is formed by molding so that its thickness (t2) y in mm will be in a region formed by interconnecting a point a (10, 1.0), a point b (10, 3.0) and a point c (20, 1.0), totaling at three points, in an xy coordinate system (x, y). This yields a high non-freezing properties and a high incombustibility of the sheet.

A light source device includes at least one discharge tube, a discharge medium sealed inside the discharge tube, and first and second electrodes for exciting the discharge medium. The first electrode is arranged inside or outside the discharge tube, and the second electrode has a plurality of contact portions at which the second electrode is in contact with an outer surface of the discharge tube. The contact portions are located at different distances from the first electrode and are provided discontinuously. Xenon gas and at least one selected from argon gas and krypton gas are sealed in the discharge tube, in which the xenon gas accounts for 60 vol % to 80 vol %. Thus, it is possible to provide a light source device and a liquid crystal display device that provide light emission with high brightness and excellent brightness distribution and that can be manufactured readily.

A discharge lamp device is provided that includes a light source device including a reflective surface. In the light source, noble gas not including mercury is excited to provide stable light emission and ozone or the like is prevented from being generated. This discharge lamp device includes airtight container (10) in which both end sections of a glass bulb are sealed. Airtight container (10) is filled with a discharge medium mainly including noble gas. One end section of airtight container (10) includes first electrode (11). Airtight container (10) is externally attached to insulating holder (20) having a square plate-like shape that includes penetration hole(s) (21) at one or a plurality of position(s). Holder (20) is fitted to second electrode (12) shaped to be a U-like groove so that a fixed interval between airtight container (10) and second electrode (12) is maintained. Three side faces (22) of holder (20) include protrusion (23) and second electrode (12) includes fitting hole (15) fitted with protrusion (23). By fitting protrusion (23) with fitting hole (15), holder (20) is prevented from disengaged from second electrode (12).
