  • Publication number: 20090087628
    Abstract: A method of manufacturing an electrooptical device includes forming a film-deposited section of function liquid droplets on a substrate by a liquid droplet ejection apparatus having a plurality of color-dependent function liquid droplet ejection heads are arranged such that a plurality of color-dependent partial imaging lines, each formed by a plurality of ejection nozzles, are formed so as to continuously make up a single imaging line in the Y-axis direction. An imaging process is performed by repeating a main scanning operation for driving each function liquid droplet ejection head in synchronization with moving of the substrate in the X-axis direction, and a sub-scanning operation for moving the function liquid droplet ejection heads through a carriage unit in the Y-axis direction by a length of a partial imaging line.

    Abstract: A negative electrode 15 includes a negative-electrode current collector 16 provided with a large number of through-holes 16a and a negative-electrode mixture layer 17 applied thereon. Positive electrodes 13 and 14 are arranged so as to sandwich the negative electrode 15. A thin positive-electrode mixture layer 20 having a high output characteristic is provided to the positive electrode 13, and a thick positive-electrode mixture layer 22 having a high capacity is provided to the other positive electrode 14. Since these positive electrodes 13 and 14 having different charging/discharging characteristics are provided, an energy density and an output density can be enhanced. Ions can move between the positive-electrode mixture layers 20 and 22 via the through-holes 16a of the negative-electrode current collector 16, whereby a variation in the potential of the positive electrodes 13 and 14 can be canceled. Therefore, the durability of the electric storage device 10 can be ensured.
