PROBLEM TO BE SOLVED: To provide a magnetic material reversion display panel which mitigates the degree of broken-off visibility of a writing line, even when the magnetic material for display gradually precipitates to the lower part of a liquid storage chamber by impact or gravity and consequently, a gap is generated in the upper part of the liquid storage chamber. SOLUTION: An inclined barrier which descends toward a transparent face sheet from a back sheet, is provided in the upper part of the liquid storage chamber.
