This invention provides a layout adjustment method of determining the layout of a page on the basis of layout information representing the intra-page layout of a plurality of partial regions in which images based on assigned data are visually drawn. An electrode 4, which is one of the electrodes constituting an element capacitor Cp, is connected to the signal line S1 via a switching element TFT1, while the other electrode 5 is connected to the signal line S2 via a switching element S2. The method further includes providing a conductive via in a first pixel of the plurality of pixels, the via disposed in the dielectric layer and electrically connecting the stationary electrode to the black mask, the via disposed in a position along an edge of the first pixel, spaced offset from the edge of the first pixel in a direction towards the center of the first pixel. The switching valve is configured to switch fluid communication to the fluid output between the first fluid input and the second fluid input.
