Electrophoretic display apparatus and electronic device having a boundary layer between an electrode and an electrophoretic layer
Abstract:
An electrophoretic display apparatus has an electrophoretic layer interposed between a first electrode and a second electrode each provided on the inner surface side of each of a pair of substrates and a boundary layer interposed between the first electrode and the electrophoretic layer. When the boundary layer has a thickness of T1 and a volume resistivity of ρ1 and the electrophoretic layer has a thickness of T0 and a volume resistivity of ρ0, the thickness and the volume resistivity of the boundary layer satisfy the formula (ρ1/T1)≧1×1013Ω, and the thickness and the volume resistivity of the boundary layer and the electrophoretic layer satisfy the formula (ρ1·T1)/(ρ0·T0)≦1/9.
