Abstract:
A method for manufacturing a thin film semiconductor device is provided which is capable of achieving simplification of manufacturing processes and of improving alignment accuracy without using a plurality of alignment masks. An alignment pattern is formed by using a resist layer having a plurality of regions each having a different film thickness corresponding to each of a plurality of patterns produced using a halftone mask having a halftone exposure region as a photomask and by forming a light transmitting portion to be an aperture pattern and by etching an underlying silicon layer. By having an underlying silicon layer exposed and implanting ions into an entire resist layer, only a main pattern region is doped with the ions.

The first transparent substrate is provided with: a transparent insulating substrate, pixel electrodes and common electrodes that are arranged alternately and substantially parallel to each other on the transparent insulating substrate, a plurality of pixels arranged in matrix form, scan lines and switching elements for controlling the electric field applied to the pixel electrodes, signal lines, and a first alignment layer. The direction of initial orientation of liquid crystal molecules in the aperture regions has an inclination of any angle θ other than 0° and 90° with respect to the longitudinal direction of the pixel electrodes. In regions other than the aperture regions, the direction of initial orientation of the liquid crystal molecules is orthogonal to the longitudinal direction of the pixel electrodes when the dielectric constant anisotropy of the liquid crystal molecules is positive, and parallel to the longitudinal direction of pixel electrodes when the dielectric constant anisotropy is negative.

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.
