ORGANIC EL DISPLAY DEVICE
Abstract:
A bank partitions a plurality of pixels and has an opening in each of the plurality of pixels. An organic layer includes a light emitting layer, and covers the bank opening. A first inorganic barrier layer is formed of an inorganic material, and covers the bank and the organic layer. A plurality of organic barrier portions are formed of organic materials, and are disposed on the first inorganic barrier layer. A second inorganic barrier layer is formed of the inorganic material, and covers the first inorganic barrier layer and the plurality of organic barrier portions. A recessed portion is formed on the bank and the first inorganic barrier layer (for example, the recessed portion is formed in an area which covers a contact hole), and a portion of the organic barrier portion is formed in the recessed portion.
