Abstract
Manufacturing method including forming, over substrate, TFT layer, planarization layer, and display element in this order. Forming of TFT layer involves forming passivation layer to cover TFT layer electrode, such as upper electrode, and to come in contact with planarizing layer. Forming of display element involves forming bottom electrode to come in contact with planarizing layer. TFT layer electrode and bottom electrode are connected by: first forming, in planarizing layer, first contact hole exposing passivation layer at bottom thereof; then forming second contact hole exposing TFT layer electrode at bottom thereof through dry-etching passivation layer exposed at bottom of first contact hole using fluorine-containing gas; then forming liquid repellent film containing fluorine on passivation layer inner surface facing second contact hole; and forming bottom electrode along planarizing layer inner surface and passivation layer inner surface respectively facing first contact hole and second contact hole.
