Abstract: A reflection-type liquid crystal display according to the invention includes two glass substrates, a transparent electrode provided on one glass substrate, an insulator film which is provided on another glass substrate and on which an uneven structure is formed, a reflecting electrode provided on the insulator film, and a liquid crystal layer sandwiched between a side of the transparent electrode and a side of the reflecting electrode. The insulator film includes a first insulating layer in which a large number of depressions isolated as surrounded by protrusions are irregularly arranged and a second insulating layer covering the insulating layer entirely. The protrusions are all connected in a network, so that if some of these protrusions have weaker adherence with an underlying layer, they can be supported by the surrounding protrusions.

Abstract: A combined wet etching method for stacked films which is capable of performing etching processes in a collective manner while controlling an amount of side-etching on each of stacked films and of making uniform side edges. In the wet etching method, two or more types of etching methods are performed in combination, on stacked films containing first and second films being deposited sequentially on a substrate and each having a different film property. The two or more types of wet etching methods include, at least, a first wet etching method in which side-etching on the first film is facilitated more than side-etching on the second film and a second wet etching method in which side-etching on the second film is facilitated more than side-etching on the first film.

Abstract: A reflector for a reflection-type LCD device is provided, which reflects efficiently incident light to the viewer's side and that suppresses the change of color tone. The reflector comprises a roughened surface having a protrusion pattern. The protrusion pattern gives inclination angle to the surface according to a specific distribution where a first component with an inclination angle value of 0null is 15% or less in area and a second component with an inclination angle value from 2null to 10null is 50% or greater in area. The protrusion pattern gives a variation range of chromaticity coordinates (x, y) on a chromaticity diagram dependent on an angle of view. The variation range is limited in a circle on the chromaticity diagram. The circle has a radius of approximately 0.05 and a center at a point corresponding to white color.

Abstract: Prior to converting a non-single crystal material of a semiconductor film into a single crystal material through the use of a laser beam, at least one dopant is introduced into whole of the semiconductor film. Then, the non-single crystal semiconductor film is irradiated with a laser beam to crystallize the semiconductor film. In this case, a ratio between quasi-fermi level of the single crystal material within one of transistor formation regions used to form transistors of different conductivity types and quasi-fermi level of the single crystal material within the other thereof is made to be between 0.5:1 and 2.0:1. Thus, transistors of different conductivity types are formed in the crystallized semiconductor film.
