Improved slate, characterized essentially by the fact that it is constituted by a base sheet of luminescent properties, covered on one of its faces by a film of transparent plastic material on which graphics can be made by a special marker that allows erasure at will of the trace, and whose graphics are visible by contrast on the luminescent zone provided by said base sheet, said luminescence being sufficient to allow the use of the slate in the dark.
