Abstract

PURPOSE:To execute display and printing at the same time, by heating one substrate of a display panel for which a liquid crystal having a thermooptical effect has been used, by an external signal, so that this heating brings an optical effect to a liquid crystal also a printing effect to heat sensitive paper, etc. CONSTITUTION:As for a liquid crystal having a thermooptical effect, a smectic liquid crystal and a cholesteric liquid crystal, or a nematic crystal liquid to which an optical activated substance has been added are used. In one electrode of a liquid crystal cell, heating elements 25, 26 are formed in advance on its inside surface and outside surface through a thermal conductive body 26. The heating element of the inside surface 25 is used for heating a liquid crystal layer, and the heating element of the outside surface 27 is used for printing to heat sensitive paper 28. A holder 29 adhere closely the heat sensitive paper to the heating element 27 as required, and is interlocked with a switch 30. When necessary write and printing have been finished, the liquid crystal displays a white memory state by turning off the switch, the heat sensitive paper and the heating element are separated, and printing is also finished.
