A display device includes: a support substrate including a display region where a plurality of display elements are arranged and a peripheral region where a drive circuit for each display element is provided in the periphery of the display region; a seal resin layer formed in at least the peripheral region; an opposed substrate bonded through the seal resin layer to the support substrate, sealing the display elements; an organic insulating film formed on the support substrate so as to insulate the drive circuit; a separation groove formed through the thickness of the organic insulating film so as to surround the display region and separate the organic insulating film into an inner portion and an outer portion; and a framelike projection formed on the opposed substrate so as to be opposed to the separation groove.
