ABSTRACT:
Liquid crystal display devices having very small cell thicknesses are obtained by means of underetching techniques. Via etching holes (17, 29, 31) an auxiliary layer (27) between a supporting plate (2) and a cover plate (14) is removed. Dependent on the technique used spacers (18) are formed at the area of the etching holes or in between the etching holes. The device obtained has a uniform thickness over large surface areas.
