PURPOSE: To improve operating characteristics without decreasing productivity of a picture display device using such a thermosensitive recording material that shows variation of continuous color developing state and color erasing state by heating at one of specified temps. preliminarily designed.
CONSTITUTION: A base panel 2 is produced by longitudinally and laterally arranging lots of heat generating elements 10. A display panel 3 is produced by laminating a thermosensitive recording material 19 on the back surface of a transparent substrate 18. The display panel 3 is joined with the surface of the body panel 2 so that the thermosensitive recording material 19 having uniform thickness is disposed on the surface of the heat generating elements 10 having low smoothness.
