Abstract: The present invention provides a display device and a television device with which it is possible to reduce the thickness of the device profile while also realizing desirable acoustic characteristics. This display device includes: a first plate-shaped object; a display module including a display element and a second plate-shaped object that supports the display element, the display module being disposed so as to face the first plate-shaped object; a liquid layer formed by sealing up a liquid between the first plate-like object and the display module; and a vibrator provided to the first plate-shaped object and/or the display module. The loss coefficient of the display device at 25° C. is 1×10−2 or greater and a thickness ratio between the first plate-shaped object and the display module is from 1:10 to 10:1.

Abstract: A glass sheet composite includes at least two sheets and a liquid layer held between the two sheets, and at least one of the two sheets being a glass sheet. In the glass sheet composite, the two sheets have been disposed so that an edge surface of one of the two sheets and an edge surface of the other sheet are not flush with each other to constitute a step portion having a stair-like shape in a cross-sectional view, and the glass sheet composite further comprising a seal material provided to the step portion to seal up at least the liquid layer.

Abstract: An optical member includes a transparent substrate containing at least one substance selected from glass, a glass ceramic, silicon, and sapphire, and having an infrared high-transmittance region in which an optical transmittance is 78% or more in a wavelength band of 700 nm to 1800 nm; and an optical interference film disposed on a main surface of the transparent substrate corresponding to the infrared high-transmittance region, wherein a transmittance of light, of the optical member, of at least one wavelength λ3 in the wavelength band of 700 nm to 1800 nm in a region of the optical member corresponding to the infrared high-transmittance region of the transparent substrate has a minimum value of 86.5% or more and has a difference between the minimum value and a maximum value of 9% or less in a range where an incidence angle is from 0 degrees to 60 degrees.

Abstract: A glass sheet composite includes a first glass sheet, a second sheet disposed opposite the first glass sheet, and a liquid layer formed by sealing up a liquid between the first glass sheet and the second sheet, in which the glass sheet composite has a plurality of vibration areas that are independent of each other in a plan view. The glass sheet composite is a diaphragm including at least one vibrator disposed on one side or both sides of the glass sheet composite. The glass sheet composite enables independent vibration at each of the vibration areas, and enables not only stereophonic or multiphonic reproduction but also local reproduction to be performed along with images. Since the diaphragm includes a vibrator, this diaphragm is excellent in sound reproduction.

Abstract: The purpose of the present invention is to provide a glass sheet composite which, when used in applications such as displays, attains preferred visibility. The glass sheet composite includes at least two sheets, a liquid layer held between two adjacent sheets of the at least two sheets, and a seal material provided to at least some of peripheries of the two sheets so as to seal up the liquid layer, in which at least one of the two sheets being a glass sheet, and the difference in photorefractive index between the liquid layer and the seal material being 0.015 or less.
