Abstract
In at least one embodiment of the disclosure, an electrophoretic display apparatus includes a first substrate. A refractive index variation layer is arranged so as to oppose the first substrate. An electrophoretic layer is arranged between the first substrate and the refractive index variation layer. A refractive index of the refractive index variation layer increases as it recedes away from the electrophoretic layer in a thickness direction of the electrophoretic layer.
