Abstract
An organic electroluminescence display device has a plurality of pixels, each of the pixels including a first portion and a second portion. The first portion has an organic light emitting element and is configured to display images. The second portion is a transparent transmission area through which an external object is visible and includes a foreign substance collecting member. The foreign substance collecting member is made of a ferromagnetic substance and is configured to receive electric current from an external current source through a connecting line and an electric field application pad. When electric current is applied to the electric field application pad, a magnetic field is applied to the foreign substance collecting member, and foreign substance in the first portion is collected by the foreign substance collecting member in the second portion, preventing the foreign substance from being deposited in the first portion.
