To form panels with an excellent break resisting property relative to breakdown and/or an improved mechanical property.

The plate is that when measured by an ISO 527 standard for a plate or film installed in a panel, it has a smooth or mold-pressed surface formed by the use of 1 or more polymer continuous films having an elastic modulus lower than PMMA by at least 30% and/or a rupture extension larger than at least 40% and an exterior layer being susceptible of an arbitrary thermal molding of acrylic polymer. The multi-layer plate is transparent or reflection-preventive, or colored or opalescent, having a low thickness in the range of 1.5-10mn.
