Abstract

PURPOSE: To avoid the overlapping of the display dots within one digit and thus to insure easy-to-see display, by providing the line electrodes forming a digit to the front or rear liquid crystal display panel in the form of a group and then distributing the electrode group to the front of rear liquid crystal display panel alternately.
CONSTITUTION: In the multi-layer matrix type liquid crystal display unit, front liquid crystal panel 11 and rear liquid crystal panel 12 are piled on each other in more thab one unit with the matrix electrode provided to each of panel 11 and 12. Row electrodes 14a, 14b... are installed on the inner surface of front glass 13 forming display panel 11, and line electrode 16 is formed on the surface of central glass 15 via a group of line electrodes 16aW16g. At the same time, row electrodes 15a, 15b...are installed on the back of glass 15, and line electrode 19 is formed to rear glass 18 forming display panel 12 via a group of line electrodes 19hW19n. Then electrodes 16aW16g plus 19hW19n are formed alternately to 11 and 12 with the number of the lines in a digit formed into a group. Thus, the overlapping of the display dots can be avoided within a digit
