Title: Liquid crystal display device
Inventor: OOIMA SUSUMU
IPC: G02F1/1333
Filed: 1990-08-10
Abstract: PURPOSE:To eliminate the unevenness of brightness on display by providing an area in which the interval between electrode substrates is made different so that the thickness of a liquid crystal layer is varied in each picture element which is sectioned by an electrode structure. CONSTITUTION:The area in which the interval between the electrode substrates is made different so that the thickness of the liquid crystal layer 4 is varied is provided in each picture element sectioned by the electrode structure. That is, a transparent film 6 constituted of an SiNx film is provided in the displaying area D of one picture element, so that the areas in which a cell gap is made different are provided. Consequently, since there are two parts, at least, where the cell gaps are made different in the picture element, the form of the interference spectrum of transmitted light is made different at the two parts, and the real transmitted light is the sum of these interference spectrums, so that the difference of the peak and the trough of the spectrum is relieved; therefore, an interference phenomenon can be reduced. Thus, the unevenness of the brightness on the display is eliminated.

Filed: 1991-07-29
Abstract: PURPOSE:To provide a spectral transmissivity measuring device by means of the two-light-flux method of a color separation prism. CONSTITUTION:A photometry means I is installed at a place where a light beam S incident on a specimen does not enter the means I when the beam is directed to go straight, and two movable mirrors 9, 10 are arranged between the specimen and the photometry means. The position of the mirror 9 and the direction of the mirror 10 are altered so that the beams of light in the respective cases are directed to the photometry means I according to four measuments, 100% transmission photometry without the specimen and three-color transmission photometry. Since the mirrors 9, 10 are also used at the time of 100% transmission photometry and the three-colors transmission photometry, the influence of the mirrors 9, 10 is offset and absolute transmissivity can be found when the transmissivity is calculated.

Abstract: PROBLEM TO BE SOLVED: To evaluate actual shielding performance of UV-ray by measuring the transmission characteristics of UV-rays directly and conveniently when a measured object e.g. a cosmetic, is provided on a basin body, e.g. the skin. SOLUTION: A linear light, i.e., a monochromatic UV-rays, is made incident into a measured object provided on a basic body having an inherent optical reflectance from the object side and the intensity of scattering reflected light is measured in order to determine the scattering reflectance of the object on the basic body.  Simultaneous equations of a function between the intensity of transmitted light and the intensity of scattering reflected light, i.e., an expression representative of the variation rate of transmitted light in the thickness direction of the object, determined while taking account of the fact that the transmitted light and the reflected light comprises a linear light component and a scattering light component, respectively, and an expression representative of the variation rate of the scattering light are solved for the intensity of transmitted light and the intensity of scattering reflected light. The UV-ray transmittance of the object on the basic body is then determined from the inherent UV-ray reflectance of the basic body and the UV-ray scattering light reflectance of the object on the basic material using a solution obtained as a function of the thickness of the object.
