Abstract

The present disclosure provides a panel and a method for manufacturing the panel. The panel includes a first substrate and a second substrate arranged opposite to the first substrate. The first substrate is provided with an electric field curing region configured to be provided with an electric field curable material. The electric field curable material is arranged between the first substrate and the second substrate and at a position corresponding to the electric field curing region. The electric field curable material is capable of being cured and/or decomposed under the action of an electric field.
