Image display device

An image display device, which displays an image at an image display medium including

• a pair of support plates, at least one of which is transparent,
• a first electrode group and a second electrode group, which are provided in respective correspondence with the pair of support plates, the first electrode group including a plurality of linear first electrodes arranged side by side, and the second electrode group including a plurality of linear second electrodes arranged side by side, which intersect the first electrodes, and
• colored particles sealed between the pair of support plates such that states of movement of the colored particles change in accordance with electric fields formed between the pair of support plates due to voltages applied to the first electrode group and the second electrode group, the image display device comprising:
• a first electrode driving component which receives an electrode designation signal, which designates an electrode belonging to the first electrode group to which voltage is to be applied, and applies voltage to the designated electrode, the first electrode driving component being capable of applying voltage to a plurality of the first electrodes of the first electrode group at the same time;
• a second electrode driving component which receives an electrode designation signal, which designates an electrode belonging of the second electrode group to which voltage is to be applied, and applies voltage to the designated electrode, the second electrode driving component being capable of applying voltage to a plurality of the second electrodes of the second electrode group at the same time;
• a line image data generation component to which image data of an image to be displayed at the image display medium is inputted, and which, using the image data, generates line image data for line images which are to be displayed along scan electrodes when the image of the image data is displayed by simple matrix driving, in accordance with a scanning direction when the image is displayed at the image display medium;
• and
• a signal output destination-switching component. in accordance with the scanning direction, which outputs a first electrode designation signal to one of the first electrode driving component and the second electrode driving component, for designating the scan electrode of the line at which the line image is to be displayed, and outputs a second electrode designation signal to the other of the first electrode driving component and the second electrode driving component, for designating an electrode to be driven for displaying the line image,
• wherein the scanning direction is changeable between a first direction and a second direction which intersect each other,
• wherein the signal output destination-switching component switches, based on the scanning direction, between
