ABSTRACT:
The invention concerns a liquid crystal display device comprising first display electrodes (31-48) and a set of second elongated display electrodes (50-56) formed on a first substrate (11;250) (10;251), and a set of elongated counter electrodes (70-129; 300-359) formed on a second substrate (10;251) facing the first substrate (11;250) and superposed with said second display electrodes (50-56) so as to create a matrix display of display elements. The counter electrodes (70-129; 300-359) are juxtaposed along substantially their whole length. The counter electrodes are also superposed with the first display electrode so as to display a fixed display symbol. Furthermore, the distance separating the counter electrodes (70-129; 300-359) from each other is substantially less than the width of said first display electrode (31-38).
