When electrodes in two-layer composition, provided with a color filter in the inside thereof, are provided on the inner surface of a liquid crystal cell board, it is aimed to prevent creation of faulty connections in contact holes and to transmit a driving voltage normally even if faulty connections may occur. A first-layer transparent electrode 1a is formed on the board, then resist is coated so that the contact holes 6 are open on the side surface in one side of the electrode pattern, on which a color filter 3 is formed. After that, said resist is removed and a second-layer transparent electrode 1b is formed in film.

Method of manufacturing color-filter-fitted board for liquid crystal

A method is provided for forming a color filter for a liquid crystal display apparatus which requires considerably reduced area on a transparent substrate for performing electrodeposition of the color filter. The method includes coating non-extended liquid crystal driving terminal portions with a protective film with a notch etched therein for exposing an end edge portion of the non-extended driving terminal; and coating the non-extended driving terminals with a transverse strip of conductive material to place the non-extended terminals into a conducting state.

Method of forming a color filter for a liquid crystal color display

A liquid crystal color display device comprises: a two-layer structured transparent electrode in an identical pattern provided on a transparent substrate forming a liquid crystal; a color filter membrane disposed between said two-layered transparent electrodes by an electrically setting method; and a plurality of pinholes of a size less than 50 .mu.m formed in a same number on each display part at the equal distance to each other in a smaller distance than the pitch between each display part, through which said first layer and second layer of the transparent electrode are electrically connected to each other. The process for manufacturing the liquid crystal color display device comprises: forming a first layer electrode; forming photoresists and coating a color filter membrane; forming a plurality of pinholes in a dot form; forming a second layer transparent electrode through three steps of tentative, main and repeating baking treatments and connecting electrically the two layers of the electrode via the pinholes.
