Abstract

PURPOSE:To enable simple and accurate positioning by forming marks for positioning by dyeing at prescribed positions of glass substrates when color filter layers are formed. CONSTITUTION:Transparent electrodes 2A, 2B are stuck to glass substrates 1A, 1B, respectively, and color filters 3A, 3B are formed on the electrodes 2A, 2B. At this time, marks 6A, 6B for positioning are simultaneously formed by dyeing at the four corners of the substrates 1A, 1B. After carrying out necessary orientation, the substrates 1A, 1B are placed opposite to each other, positioned properly with the marks 6A, 6B, and adhered with an adhesive 4 to manufacture a cell.
