To provide: a novel and improved optical object in which the rugged structure of the optical film can be protected without requiring the use of a protective film, the optical film can have a reduced thickness, the handleabilty can be improved, the occurrence of a trouble attributable to a difference in refractive index between an adhesive layer and the optical film is inhibited, and the optical film can be more tenaciously adhered to an adherent; an optical-film laminate; and a process for producing the optical object. The optical object according to the present invention comprises an optical film equipped with a first rugged structure formed in one surface thereof and a second rugged structure formed in the other surface and a master film covering the first rugged structure, wherein the first rugged structure has an average ruggedness period which is not greater than the wavelengths of visible light and the master film is equipped with a third rugged structure that has been formed in the surface facing the first rugged structure and that has a shape reverse to that of the first rugged structure.

An optical lens in which reflection is suppressed is provided by providing the optical lens with: a convex lens surface having, when the angle between a plane in contact with the lens surface and a direction perpendicular to the optical axis is an inclination angle, a maximum inclination angle of not less than 35 degrees and less than 90 degrees; and an antireflective structure provided on the lens surface and including structural elements that have a predetermined shape and are periodically arranged in an array form with a pitch smaller than the shortest wavelength of the incident light.

Wet-recess (develop) gap-fill and bottom anti-reflective coatings based on a polyamic acid or polyester platform are provided. The polyamic acid platform allows imidization to form a polyimide when supplied with thermal energy. The gap-fill and bottom anti-reflective coatings are soluble in standard aqueous developers, and are useful for patterning via holes and trenches on semiconductor substrates in a dual damascene patterning scheme. In one embodiment, compositions composed of polyamic acids can be used as gap-filling (via-filling) materials having no anti-reflective function in a copper dual damascene process to improve iso-dense fill bias across different via arrays. In another embodiment, the same composition can be used for anti-reflective purposes, wherein the photoresist can be directly coated over the recessed surface, while it also acts as a fill material to planarize via holes on the substrate. The compositions described here are particularly suitable for use at exposure wavelengths of less than about 370 nm.

A light emission section includes light generators which are operated on the basis of drive signals from a controller so as to emit near infrared interferable light beams having different specific wavelengths to a light interference section. The light interference section includes a beam splitter having a low-reflection region. The beam splitter allows a most portion of the near infrared interferable light beams to propagate toward an object to be examined, and reflects a portion of the near infrared interferable light beams to a movable mirror. The beam splitter causes interference between measurement light reflected by the object and reference light reflected by the movable mirror, and the resultant interference light propagates to a light detection section. The light detection section receives the interference light and calculates predetermined information regarding the object by making use of the quantity distribution of the interference light. A display section displays the calculated information.

An optical scanner includes: a movable body that is able to oscillate around a first axis; a first shaft member that is connected to the movable body along the first axis; and a drive unit that includes a permanent magnet, a coil that generates a magnetic field by application of voltage, and a voltage applying section that applies a voltage to the coil and oscillates the movable body around the first axis, wherein the movable body includes a light reflecting plate provided with a light reflecting section having light reflectivity, a support frame that surrounds the light reflecting plate and has a thickness that is, ten times or less, larger than the thickness of the light reflecting plate, and a plurality of connecting sections that connects the light reflecting plate and the support frame at a plurality of locations.

Diffractive patterns are disposed on a MEMS substrate in the gaps between the MEMS micromirrors to reduce backreflection of light leaking through the gaps and reflected by the MEMS substrate. The diffractive patterns are silicon surface-relief diffraction gratings or silicon oxide gratings on silicon substrate. Sub-wavelength gratings are used to suppress higher orders of diffraction; 50% duty cycle surface relief gratings on a substrate having index of refraction close to 3 are used to suppress both reflected and transmitted zero orders of diffraction simultaneously. The gratings have lines running parallel or at a slight angle to the gaps, to prevent the diffracted light from re-entering the gaps.

A light-emitting device includes a transparent substrate, a light-emitting layer which is provided on one surface of the substrate and which emits light in response to an electrical signal, a conductive portion which transmits the electrical signal to the light-emitting layer, such that light from the light-emitting layer is emitted after being transmitted through the substrate, and a light transflective layer which is provided between the conductive portion and the substrate at a predetermined distance from the conductive portion to reflect some of incident light through the substrate and to transmit the remainder.

A display device may include a substrate, a color filter layer, on a first surface of the substrate, including a red color filter, a green color filter, a blue color filter, and a gray color filter, and an organic light emitting diode on the color filter layer. The gray color filter may have a blue light transmittance higher than red and green light transmittances.

An object is to provide a manufacturing method of a functional film where it is possible to stably manufacture a functional film which favorably exhibits the intended function and has excellent optical characteristics. The problem is solved by forming an uppermost organic layer of an organic layer with a thickness of 30 to 300 nm by using a coating material containing a surfactant where the content is 0.01 to 10 mass % when the uppermost organic layer is formed.

A display includes: a laminated wiring with a conductive film arranged on a foundation layer, and a transparent film and a translucent film arranged on the conductive film; a wiring terminal part arranged at an edge portion of the laminated wiring and having the same laminated structure as that of the laminated wiring; and an insulating film that covers the laminated wiring and the wiring terminal part.
