  • Patent number: 7537948
    Abstract: To provide an electro-optical device having a buffer layer which planarizes a gas barrier layer so that stress-concentration in the gas barrier layer is reduced, the buffer layer being prevented from leaking out of a predetermined area, and to provide a method of producing the same and an electronic apparatus. In an electro-optical device 1 having, on a substrate 200, a plurality of first electrodes 23, a bank structure 221 having a plurality of openings 221a positioned correspondingly to the formed first electrodes, electro-optical layers 60 arranged in the respective openings 221a, and a second electrode 50 covering the bank structure 221 and the electro-optical layers 60, the device includes a buffer layer 210 formed so as to cover the second electrode 50 and have a substantially flat upper surface, a frame 215 made of a material having no affinity to the buffer layer 210 and surrounding the periphery of the buffer layer 210, and a gas barrier layer 30 covering the buffer layer 210 and the frame 215.
