[0116] Next, an active matrix liquid crystal display according to a second embodiment of the present invention will be described. The structure of the liquid crystal display of the second embodiment is similar to the aforementioned Figure 5-8 The first embodiment shown in ; therefore, a description of exactly the same will be omitted.

[0117] In the second embodiment (see Figure 7 ), the uppermost surface of the TFT array substrate 10 corresponds to the surface of the pixel electrode 9 covering the prescribed area of ​​the third insulating film 7 and the surface of the third insulating film 7 not covered by the layer of the pixel electrode 9 . On the uppermost surface of the TFT array substrate 10, an inorganic alignment film 36 is formed using an inorganic material such as silicon oxide by an oblique deposition method. The inorganic alignment film 36 is composed of at least one type of columnar structure in which columns are arranged and inclined in a specific direction....

Abstract

An active-matrix liquid crystal display is composed of an active matrix substrate, a liquid crystal, and an opposite substrate having a common electrode. The active matrix substrate fabricates a first group of pixel electrodes that are aligned and supplied with picture signals of a first polarit, and a second group of pixel electrodes that are aligned to adjoin with the first group of pixel electrodes respectively and are supplied witb picture signals of a second polari. An inorganic orientation film is formed on the surfac of the active matrix substrate to provide a first orientation direction (Ra) to its proximal liquid crystal moleclges, while an organic orientation film is formed on the surface ofthe opposite substrate to provide a second orientation direction Rb, rectangularly crossing the first oneenation direction, to its proximal liquid-crstal molecules.

Description

[0001] This application is a divisional application of application number 02108087.9. technical field [0002] The present invention relates to liquid crystal displays, in particular active matrix liquid crystal displays for use in electronic devices such as color image projectors, the displays having row inverse drive and column inverse drive operation. Background technique [0003] Typically, liquid crystal displays of the projection type (referred to as liquid crystal display projectors) employ active matrix liquid crystal displays as their liquid crystal light valves, which act as light modulators. An active-matrix liquid crystal display comprises an active-matrix substrate on which signal lines, electrodes and switching elements for pixels are constructed, and its opposite substrate with a common electrode, wherein the substrates are arranged opposite to each other. The sheets are separated from each other by a prescribed gap through the sealing material. Liquid crysta...
