A light source device capable of suppressing generation of color unevenness, and a display device using the same are provided. The light source deviceis provided with a plurality of excitation light sourceswhich are arranged at prescribed intervals D on a substrateand emit blue light, and a phosphor layerwhich converts part of the blue light emitted from the excitation light sources into red light and green light and arranged at a distance from the excitation light sourcesto oppose the substrate. Fluctuation of intensity of each color light due to nonuniform application of the phosphor layer is difficult to occur as compared with a configuration in the past where the phosphor layer is formed adjacent to each excitation light source.

Light source device and display device

A manufacturing method for a liquid lens device includes: preparing a body having a liquid chamber, a conductive first liquid stored in the liquid chamber, an insulating second liquid stored in the liquid chamber, an electrode kept in contact with the first liquid, and a liquid discharge passage for making the communication between the inside and the outside of the liquid chamber; applying pressure to the first and second transparent substrates to thereby compress the sealing member and discharge the first liquid through the liquid discharge passage to the outside of the liquid chamber; and closing the liquid discharge passage.

Liquid lens device and manufacturing method therefor

Disclosed herein is an optical device including: a light-transmitting first main body which constitutes a part on a light incidence side; a light-transmitting second main body which constitutes a part on a light outgoing side; a third main body which is stacked between the first main body and the second main body in a second direction orthogonal to the first direction, and which defines a liquid chamber between the first main body and the second main body; a lens surface which is formed by an interface between a plurality of liquids differing in refractive index and sealed in the inside of the liquid chamber, and which is electrically deformable; and a jig which clamps the mutually stacked first main body, second main body, and third main body in the second direction by the third engaging part and the fourth engaging part.

Optical device, electronic apparatus, and method of manufacturing optical device

A manufacturing method for a liquid lens device includes the steps of: preparing a body having a liquid chamber, a conductive first liquid stored in the liquid chamber, an insulating second liquid stored in the liquid chamber, and a hollow electrode pipe for making the communication between the inside and the outside of the liquid chamber, the liquid chamber being defined by a first transparent substrate on which an electrode layer is formed, a second transparent substrate opposed to the first transparent substrate, and an annular sealing member interposed between the first transparent substrate and the second transparent substrate; applying pressure to the first and second transparent substrates to thereby compress the sealing member and discharge the first liquid from the second end of the hollow electrode pipe; and closing the second end of the hollow electrode pipe.

A semiconductor light-emitting device having a semiconductor light-emitting chip; a high refractive index lens covering around the semiconductor light-emitting chip; and a resin having fine particles mixed therein that fills a space between the semiconductor light-emitting chip and the lens is provided. In the semiconductor light emitting device, the resin having fine particles mixed therein is composed of an optically transparent resin into which a large number of high refractive fine particles having a mean diameter of 100 nm or less and composed of a dielectric material are mixed uniformly to have a distance 200 nm or less between respective particles.
