To provide a substrate equipped with a plurality of color elements having almost fixed cross-sectional shapes and its manufacturing method, to provide an electro-optical device using the substrate and its manufacturing method, and to provide an electronic apparatus carrying the electro-optical device.
In this substrate 1, a plurality of color elements regions A of an element substrate 2 are partitioned, and it is equipped with a two layer bank 13 having a step on a wall surface, and electrodes 12 and hole injection transport layers 16 formed on a plurality of the color element regions A. It is also equipped with three kinds of light emitting part 17 formed by granting three kinds of functional liquid 40, 41, 42 containing a luminous layer forming material to a plurality of the color element regions A. The two layer bank 13 consists of a lower layer bank 14 and an upper layer bank 15 partitioning the color element regions A, and the lower layer bank 14 is provided so as to stretch out to the inside of the color element region A to form the step on the wall surface of the two layer bank 13. In addition, the amount of the lower bank 14 stretching out to the inside of the color element region A differs according to the functional liquids 40, 41, 42 given to the color element regions A.
