Abstract

The present invention provides a display device substrate, a display device substrate manufacturing method, a display device, a liquid crystal display device, a liquid crystal display device manufacturing method and an organic electroluminescent display device that allow suppressing faults derived from occurrence of gas and/or bubbles in a pixel region. The present invention is a display device substrate that comprises: a photosensitive resin film; and a pixel electrode, in this order, from a side of an insulating substrate. The display device substrate has a gas-barrier insulating film, at a layer higher than the photosensitive resin film, for preventing advance of a gas generated from the photosensitive resin film, or has a gas-barrier insulating film, between the photosensitive resin film and the pixel electrode, for preventing advance of gas generated from the photosensitive resin film.
