Abstract
A plane display apparatus in which R, G and B liquid crystal cells are isolated from each other by means of partition walls, and a pair of ITO electrodes are formed on each of the cells and between a pair of substrates, wherein the cells can be arranged either in a matrix form or in a linear form and each pair of the ITO electrodes is supplied with a single voltage, the liquid crystal cells having different driving characteristics respectively.
