Patent ID: 7956537

Claim:
A display device comprising: a support substrate including (a) a display region where a plurality of display elements are arranged and (b) a peripheral region about a periphery of the display region and including a drive circuitry for said display elements; an opposed substrate; an organic insulating film over said support substrate so as to insulate said drive circuitry; a seal resin layer over the organic insulating film within at least the peripheral region; at least one separation groove within the peripheral region, said groove extending through the thickness of said organic insulating film and extending around said display region so as to surround said display region and separate said organic insulating film into an inner portion and an outer portion; and at least one first projection and at least one second projection both extending from said opposed substrate in a same direction within the peripheral region, the first and second projections being framelike projections, and the second projection being lower in height than said first projection with reference to the opposed substrate, wherein, said seal resin layer extends into said separation groove, said first projection is received within said separation groove with said seal resin layer between said first projection and inner walls and bottom of said separation groove, and said second projection is opposite said organic insulating film in a region outside the separation groove with said seal resin layer between said second projection and said organic insulating film, and said opposed substrate is bonded to said support substrate by means of said seal resin layer.
