An antireflection film capable of reliably preventing light (or laser light), which is incident on a glass substrate and which reaches a metal film, from being reflected by the metal film. The antireflection film provided between a metal film having a complex refractive index represented by NM=nM−i·km and a glass substrate having a refractive index NG includes, from the metal film side: (A) a first dielectric layer having a refractive index N1; (B) a second dielectric layer provided on the first dielectric layer and having a refractive index N2; and (C) a third dielectric layer provided on the second dielectric layer and having a refractive index N3, in which N1 NG, N2 NG hold. Accordingly, light which is incident on the glass substrate and which reaches the metal film is prevented from being reflected by the metal film.

The present invention has been made to form a reflecting polarizer without using a high-birefringence polymer. The present invention provides a reflecting polarizer that transmits a first linear polarization component that oscillates parallel to a first polarization plane of an incident light and reflects a second linear polarization component that oscillates parallel to a second polarization plane perpendicular to the first polarization plane by utilizing birefringence characteristics to polarize/split the incident light, comprising a dielectric multilayer film obtained by stacking, a plurality of times in an alternate manner, a high refractive index layer formed using a dielectric material having birefringence characteristics, and a low refractive index layer formed using a dielectric material having a refractive index which is substantially the same as one of the refractive indexes that the dielectric material having birefringence characteristics has.

Signals are provided which allow colors in a wider color range than predetermined standards, which can be handled by apparatus according to such predetermined standards. A primary color converter converts first color signals having primary color points in a wider color range than the primary color points according to BT.709 into second color signals based on the primary colors according to BT.709. A photoelectric transducer converts the second color signals into third color signals according to photoelectric transducer characteristics defined in a numerical range wider than a range from 0 to 1.0 of color signals corresponding to a luminance signal and color difference signals according to BT.709. A color signal converter converts the third color signals into a luminance signal and color difference signals. A corrector incorporated in the color signal converter corrects the color difference signals into color difference signals.

There is provided a lens formed from a circular bottom face (11), lateral face (14) and top face (15) and having a surface light source (13) of a finite size disposed at the center of the bottom face (11). The top face (15) is an aspheric surface rotational symmetric with respect to a z-axis and which totally reflects a part of a component, whose polar angle is smaller than a polar angle Θ0 at the intersection between the lateral face (14) and top face (15), of light emitted from the surface light source (13). The lateral face (14) is an aspheric surface rotational symmetric with respect to the z-axis and pervious to a component, whose polar angle is larger than the polar angle Θ0, and component, totally reflected at the top face (15), of the light emitted from the surface light source (13). A function r=fS(z) where z is a variable representing the lateral face (14) increases monotonously as the variable z decreases in a closed zone defined by 0≦z≦z1 (z-coordinate of an intersection between the lateral face (14) and top face (15)), and has at least one point where a absolute value |d2r/dz2| is maximum in the closed zone.
摘要:
A laser annealing device (10) includes a laser oscillator (12), radiating a pulsed laser light beam of a preset period, and an illuminating optical system (15) for illuminating a pulsed laser light beam to an amorphous silicon film (1). The illuminating optical system (15) manages control for moving a laser spot so that a plural number of light pulses will be illuminated on the same location on the amorphous silicon film (1). The laser oscillator (12) radiates a laser light beam of a pulse generation period shorter than the reference period. The reference period is a time interval as from the radiation timing of illumination of a pulsed laser light beam on the surface of the film (1) until the timing of reversion of the substrate temperature raised due to the illumination of the laser light beam to the original substrate temperature.
