| 1. A display apparatus, comprising:
an electrophoretic display device having a plurality of pixels arranged in a matrix, each pixel including charged particles
in a dispersion liquid and a pair of electrodes disposed close to the dispersion liquid, and a position of the charged particles
in the pixel providing a gradation, and
a drive circuit for outputting a gradation signal to each pixel, wherein
the gradation of each pixel is influenced by gradation signals of adjacent pixels through an electric field interference between
pixels, and
further comprising a correction circuit for correcting the gradation signal at each pixel to compensate for the influence
from the gradation signals of the adjacent pixels.
