Abstract: A display device includes a lower inorganic barrier layer. Pad electrodes are disposed on the lower inorganic barrier layer and penetrate the lower inorganic barrier layer. The pad electrodes are spaced apart from each other. An upper inorganic barrier layer is disposed on the lower inorganic barrier layer and covers the pad electrodes. An upper organic base layer is disposed on the upper inorganic barrier layer. A circuit layer is disposed on the upper organic base layer. A light emitting element layer is disposed on the circuit layer. A lower organic base layer is disposed under the lower inorganic barrier layer. The lower organic base layer includes a first portion defining contact openings respectively exposing the pad electrodes penetrating the lower inorganic barrier layer. A second portion is disposed under the first portion. The second portion defines a pad opening exposing the contact openings.
