Methods of manufacturing a sapphire seed for growing a crystal having reduced dislocation density. The present invention provides a method of manufacturing a sapphire seed formed by a sapphire single crystal and used for growing another sapphire single crystal on a (0001) face as a crystal growing surface, the method comprising: preparing a sapphire seed whose side face forms a crystal face within a {1-100} face±10°, and whose shape is processed so as to include a hexagonal prism or a triangle prism; and applying a predetermined thermal treatment to said sapphire seed.

A mask for photolithography in which a semi-transmission film is formed so that the phase difference of lights passing through a semi-transmission portion and a transmission portion of the mask for photolithography is between (−¼+2 m) π and (¼+2 m) π inclusive, where m is an integer. The invention makes it possible to efficiently and properly form a thin film having a multi-step structure by a single process.

A liquid crystal display device, by which a reduction of costs of a color filter is realized and declining of the transmittance or reflectance due to an alignment error is suppressed, comprising a pair of substrates arranged facing to each other over a liquid crystal layer, wherein one substrate is formed pixels PXL arranged in matrix. Each pixel is formed a reflection portion for reflecting an outside light and a transmission portion for transmitting a light. The other substrate is formed a color filter colored to be different colors (red, green and blue) corresponding to respective pixels. One or more color adjusting windows CFW having a coloring concentration of zero or less than that of other portions are provided on reflection regions CFR superposing with reflection portions inside pixel regions corresponding to respective pixels.

A liquid crystal display device includes a first substrate, a second substrate, and a liquid crystal layer interposed between the first and second substrates. The first substrate includes a protrusion structure and a vertical alignment layer each facing the liquid crystal layer. The liquid crystal layer includes a plurality of liquid crystal regions separated from each other by the protrusion structure. Liquid crystal molecules in the plurality of liquid crystal regions are aligned axially symmetrically around an axis perpendicular to a surface of the second substrate at least in the presence of applied voltage. Each of the plurality of liquid crystal regions has a size such that each of the plurality of liquid crystal regions is included within a circular area circumscribing a square of approximately 70 &mgr;m or less.

A plasma address liquid crystal display device having a flat panel structure which is composed of display cells and plasma cells bonded to one another with an intermediate sheet, and in which position registration tolerance between the display and plasma cells can be made less strict. A plasma cell 2 has discharge channels 5 extending in the row direction. The display cell 1 has a electro-optical device 9 and signal electrodes 10 extending along the column direction. Pixels 11 are defined at the points of intersections of the signal electrodes 10 and the discharge channels 5. The electro-optical device 9 is a set of finely partitioned liquid crystal areas 15 and is controlled in orientation to axis-symmetrical orientation. The liquid crystal areas 15 are continuously arrayed at a constant pitch DP finer than an arraying pitch CP of the pixels 11 at least in the column direction. This structure can be extensively applied to the active matrix type liquid crystal display device.
