IPC: G09F9/00
Filed: 1988-05-16
Abstract: PURPOSE:To extremely facilitate large-area display and to inexpensively produce the display device without using polarizing plates, etc., by coating a material which is colored or discolored reversibly by a thermal change on a panel-shaped transparent conductive heating element. CONSTITUTION:The panel-shaped transparent conductive heating element 2 generates heat as current flows therein if said heating element 2 is coated on an arbitrary substrate 3 and when a voltage is impressed thereto. The material which is colored or discolored reversibly by the heat is otherwise coated on the panel-shaped hating element 2. For example, a chloesteric liquid crystal is used for the material which is changed in color. Since the pitch of the cholesteric liquid crystal changes reversibly with temp., the change of the color is reversible and is extremely bright and is further sensitive to temp. A transparent conductive electrode consisting of a semiconductor called as, for example, 'NESA (R)' is preferably used for the heating element. The large-area display is inexpensively produced in such a manner.
