Zusammenfassung:	PURPOSE:To obtain an oriented film which is formed not by a rubbing method and to obtain uniform liquid crystal orientation performance having almost no defect by setting the contact angle of liquid crystal on the oriented film to 10 - 20 deg. and performing orientation almost by the oriented film itself. CONSTITUTION:One electrode body 2a which is used for the liquid crystal element 1 consists of a glass substrate, a transparent electrode 5a formed on the glass substrate 4, and an oriented film 6 formed on the surface of the transparent electrode 5a and the other electrode body 2b consists of a glass substrate 4, an electrode 5b formed on the glass substrate 4, an electrode 5b formed on the glass substrate 4, and an oriented film 6 formed on the surface of the electrode 5b. Then the oriented films 6 uniform the molecule array of the liquid crystal 3 and has such surface property that the contact angle theta of the liquid crystal 3 is 10 - 20 deg., and nearly oriented thin films are used. Consequently, the oriented films 6 which are formed without rubbing are formed and the uniform orientation of the liquid crystal with almost no defect and a proper pretilt angle are obtained.
