Title: Liquid crystal display device
Inventor: JINGU KEIJI
IPC: G02F1/133
Filed: 1988-10-25
Abstract: PURPOSE:To allow black and white display by providing a uniaxial high-polymer film having specific absorption spectra in a visible wavelength region between a pair of polarizing plates. CONSTITUTION:This display device has an upper polarizing plate 1, the uniaxial high-polymer film 2, a liquid crystal 3 for display, and a lower polarizing plate 4. Further, the device has an upper electrode substrate 5, a lower electrode substrate 6, and a twist-oriented liquid crystal 7. The linearly polarized light which is passed through one of a pair of the polarizing plates 1, 4 passes the liquid crystal layer of the liquid crystal cell 3 for display and the uniaxial high-polymer film 2 which is an optically anisotropic body, by which the light is made into the elliptically polarized light nearly unified in the major axis direction. Since the major axis of the elliptically polarized light is nearly unified, the strong absorption of only the certain wavelength region is obviated when the light passes another polarizing plate. The appearance of the liquid crystal display device has a nearly white color in a no-voltage impressed state and a nearly black color in a selection voltage impressed state.

Title: Interferometer for measuring shape of surface, wavefront aberration measuring machine, manufacture of projection optical system using this interferometer and machine, and method for calibrating this interferometer
Inventor: ICHIHARA YUTAKA
IPC: G01M11/00
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a highly efficient projection optical system by causing the light beams from an optical surface and a reference surface to interfere with each other in a state where the optical and reference surfaces are united in one body and measuring the shape of the optical surface and wavefront aberration, and then, calculating the shape correcting amount of the optical surface based on the obtained information. SOLUTION: After the light beam from a laser 1 is transformed into parallel rays of light, the parallel rays of light are transformed into an aspherical shape by making the rays incident to a null element 2 and perpendicularly made incident to an aspherical reference surface 3 and an aspherical test surface 4. The reference surface 3 has a substantially same shape as the test surface 4 has and a holder 6 integrally holds the surfaces 3 and 4 in a closely arranged state. The light beam from the reference surface 3 is reflected by the surface 4 and is made incident to the reference surface 3 as a wavefront to be measured. For calibration, the shape of the aspherical test surface 4 is measured and the surface is correctively polished until the surface becomes coincident with designed data. Then the wavefront aberration is measured.  The factor causing the aberration is decomposed into an alignment error and a form error. When the errors are small, a system error is calculated from the difference between the form error in the wavefront aberration and aspherical shape data and, after correcting the aspherical data by the difference, the test surface 4 is repolished.

Title: Diffraction grating display
Inventor: TODA TOSHITAKA
IPC: G02B5/18
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To avoid the crosstalk between cells, and to stably and visually sensed a display by changing the ratio of the grating width to the grating period at each position in a diffraction grating cell so as to realize the intensity distribution in which the primary diffracted light from a cell comprising a binary diffraction grating becomes weaker from a center part of the cell to the peripheral part in one direction of a cell surface. SOLUTION: The intensity of the outgoing light in a main lobe is uniformized, while the intensity of the noise light outside the main lobe is reduced by changing 'the ratio of the grating width to the grating period' of a diffraction grating in a diffraction grating cell which is a pixel from a center part to a peripheral part at least in one direction. When the amplitude distribution of the primary diffracted light immediately behind the cell is changed by the ratio modulation of the diffraction grating in the cell, the intensity at the peripheral part can be reduced even when the primary diffracted light immediately behind the cell has the phase distribution of spherical wave shape. In such a cell, the intensity distribution of the primary diffracted light tends to be uniformized.
