    • PURPOSE:To distinctly, rapidly and easily display a coat line by selectively energizing plural electrical display means disposed in a floor surface part by a selective energizing means and displaying the coat line by light emission or color development. CONSTITUTION:This electrical display means 12 is constituted by clamping a luminous body 15 between electrodes 13 and 14 and is housed in a groove 17 disposed in a floor surface part 16. A transparent sheath 18 is applied on the front surface side. Electric power is applied to the electrodes 13, 14 of the electrical display means 12 by a selective energizing means 23 consisting of lead wires 19, 20, a power source 21 and a switch 22. Consequently, the luminous body 15 emits light, by which a prescribed line width L is obtd. The luminous intensity of the luminous body 15 is freely changed by changing the electric power to be energized. The electric power is selectively applied according to code patterns to the plural electrical display means 12 or the electrical display means is constituted to have a band-shaped electrical heating element and a temp. sensitive color developing element disposed on the front surface of this heating element.
