Display unit and electronic apparatus
A display unit is provided with a plurality of pixels that are two-dimensionally arranged and each include an organic electroluminescence element emitting light of one of a plurality of colors. The pixels are arranged along one direction for each of light emission colors. The pixels each include a first insulating film, a second insulating film, and an organic layer. The first insulating film has openings for the respective pixels. The second insulating film extends along the arrangement direction for each of the light emission colors, in a region between pixels of different light emission colors, out of the plurality of pixels, on the first insulating film. The organic layer is formed in each of the openings, and includes a light-emitting layer. The first insulating film includes a recess that connects together the openings of pixels of the same light emission color, out of the plurality of pixels.
