A display apparatus comprises a first substrate provided with a thin film transistor array as a driving switching element and a second substrate provided with another electrode, and produces a display by electro-optical change generated between these substrates. Visibility of the display is improved in such a way that rays of light incident on the display apparatus are converted into diffusion light. Photoconductive material, in particular amorphous silicon, can be used by covering semiconductive portions of the thin film transistor array of the display apparatus with an intercepting member. In a display apparatus using a thin film transistor array as a driving switching element, a conductive surface electrically insulated from gate lines on a substrate on where the gate lines for the thin film transistor array are formed, such conductive surface acts as a counter electrode of capacitors for storing charge. Therefore the counter electrode of capacitors is separately formed from gate lines, and writing driving voltage can be set without taking effects of voltage change of gate lines into consideration. Shading layers comprising a plurality of color filters also cover each of the thin film transistors.

A method for orienting a liquid crystal comprises bringing a liquid crystal into contact with a heat treated surface of an electrode substrate provided with a film formed by coating a silane compound having alkoxy and an organic residue having at least a fluorine-substituted hydrocarbon residue, the heat treatment being effected under vacuum or under the conditions that the heating temperature and the treating time are within the region of a triangle having the vertexes at (1.75, 0), (2.5, 0) and (1.75, 3.7) in a coordinate with 1000 x (x being the reciprocal of absolute temperature) on the abscissa and ln k' on the ordinate where k' is the ratio of 300 min. to the treating time (min.).Liquid crystal display devices utilize the electrode substrate thus treated.
