Abstract
A device comprising a first layer, a sealing layer and a resin layer stacked in that order and an organic layer arranged between the first layer and the sealing layer in a pixel region is provided. The first, sealing and resin layers have openings for exposing an electrode in a peripheral region. The sealing layer includes second and third layers each having a water permeability lower than the first layer, and a fourth layer arranged between the second layer and the third layer and having a defect density lower than the second layer. A step of the second layer arranged above the end of the opening of the first layer is covered with the fourth layer and a step of the third layer arranged above the end of the opening of the first layer is covered with the resin layer.
