| 摘要 |
The present invention provides a display device which can prevent the deterioration of a transparent conductive film attributed to a cell reaction without pushing up a cost of a film forming device. The display device includes a first conductive layer which is formed of a transparent conductive film containing indium oxide as a main component, a conductive background layer which is formed on the first conductive layer, a second conductive layer which is formed of a film containing Al as a main component on the background layer, and a third conductive layer which is formed of the same material as the second conductive layer on the second conductive layer. On an interface between the second conductive layer and the third conductive layer, positions of grain boundaries are arranged discontinuously. Further, the background layer is a film which contains any one of Mo, Ti and Ta as a main component. Still further, the third conductive layer is used as a reflective electrode.
