Backlight device and display apparatus

摘要

A backlight device comprises a surface luminescent body and a light control section. The surface luminescent body includes a surface luminescent layer and first and second electrode layers sandwiching the surface luminescent layer. The light control section supplies a drive signal to the first and second electrode layers to cause the surface luminescent body to emit light. At least one of the first and second electrode layers is divided into a plurality of electrode pieces. The light control section supplies the drive signal individually to the plurality of electrode pieces.
