ABSTRACT:
A color display element comprising a first substrate, a first electrode, a first dimmer layer in which light-scattering and transparent states can be controlled by an external electric field, a color filter, a second dimmer layer in which light-scattering and transparent states can be controlled by an external electric field, and a second substrate, each disposed in the above order as viewed from the side from which light enters, a light-absorbing layer being provided behind said second dimmer layer as viewed from the side from which light enters to absorb the light which passes through said first dimmer layer, color filter and second dimmer layer.
