PURPOSE: To obtain a plane panel type liquid crystal display device which can be substituted sufficiently with CRTs by using an endless film (belt) for displaying deposited uniformly with microcapsules of smectic liquid crystals.

CONSTITUTION: A film for displaying produced by coating the microcapsules 2 prepd. by sealing smectic liquid crystals which assume a light scattering state when heated and quickly cooled and assume a transparent phase when heated and slowly cooled in transparent materials on a film base 1 and further providing an abrasion resistant resin layer 3 thereon is used. More specifically, the above-mentioned film for displaying is wound endlessly on motors 6, 7 which revolve in an arrow direction. A thermal head 5 which is movable in the direction vertical to the plane of the figure is provided via a stanchion 10 and heating and slow cooling devices 8, 9 for erasing are provided, whereby a liquid crystal display device is formed. With the above-mentioned device, the film for displaying is selectively heated and quickly cooled with the head 5 to form the phase-transferred microcapsule parts 2b thereby displaying images (a symbol 2a is a non-changing part). On the other hand, the displayed images are erased with the devices 8, 9.
