Abstract
A display device is provided which includes: lower electrodes each have a light-reflective first metal material layer and a second metal material layer provided thereon which has a superior alkaline-solution resistance to that of the first metal material layer; an insulating pattern which is formed from a photosensitive composition material, which has opening portions to expose the lower electrodes, and which covers peripheries of the lower electrodes; organic layers each of which at least include an organic light emitting layer and which are provided in the opening portions so as to cover the lower electrodes; and a light-transmissive upper electrode provided to sandwich the organic layers with the lower electrodes.

A display device comprising:
- lower electrodes each include a light-reflective first metal material layer and a second metal material layer, provided thereon which has a superior alkaline-solution resistance to that of the first metal material layer;
- an insulating pattern which is formed from a photosensitive composition material, which has opening portions to expose the lower electrodes, and which covers peripheries of the lower electrodes;
- organic layers each of which at least include an organic light emitting layer and which are provided in the opening portions so as to cover the lower electrodes;
- and
- a light-transmissive upper electrode provided to sandwich the organic layers with the lower electrodes.
A method for manufacturing a display device, the method comprising:
- forming lower electrodes each including a light-reflective first metal material layer and a second metal material layer provided thereon which has a superior alkaline-solution resistance to that of the first metal material layer;
- forming an insulating pattern by a lithographic method which has opening portions to expose the lower electrodes and which covers peripheries of the lower electrodes;
- forming organic layers each at least including an organic light emitting layer in the opening portions so as to cover the lower electrodes;
- and
- forming a light-transmissive upper electrode to sandwich the organic layers with the lower electrodes.
