    Abstract: A diaphragm for a planar speaker and a planar speaker having a long-term stability and a high reliability and exhibiting a flat sound pressure frequency property. The diaphragm for a planar speaker includes a voice coil formed by winding a wire conductor, two adhesive layers sandwiching the voice coil therebetween, and bases bonded to the two adhesive layers on the side opposite to the voice coil. The planar speaker employs the diaphragm.

    Abstract: A reflecting base material that can reliably prevent the occurrence of uneven brightness, a backlight unit that uses the same, and a method for manufacturing the same are provided. Surface profile information of the reflecting base material 7 is obtained by a laser displacement gauge 3. Next, the unevenness information obtained is subjected to Fourier transform, and the relationship between frequency and intensity for the surface unevenness profile of the reflecting base material is obtained. Next, the calculated relationship between the frequency and intensity is compared with a preset standard data. When the intensity exceeds 0.6 at a predetermined range of frequency domain, a judgment of rejection is made; when no data exceeding 0.6 exists in said judgment domain, a judgment of acceptance is made.

    Abstract: An optical attenuator (8) has a substrate (glass substrate) (1) and an optical attenuation film (2) that attenuates an input light with a predetermined optical attenuation factor, and the optical attenuation film (2) is disposed on a light input face (3) of the substrate (1). An angle defined by the light input face (3) and the light output face (4) of the substrate (1) is set to 0.15° to 0.5°. A protective film (5) for preventing the deterioration of the optical attenuation film (2) is formed on a surface of the optical attenuation film (2).
