The present invention provides an image display device which suppresses the generation of sparks between end portions of divided portions and an anode when data signal lines are divided in two. Within a display region, between scanning lines GAN, GB1, data signal lines are divided in two in one direction of the data signal lines, that is, into upper data signal lines DA and lower data signal lines DB. Assuming a width of the data signal lines DA, DB as W, and a distance between opposedly-facing end portions of the divided electrode portions as S, and a pitch of the data signal lines as P, by establishing a relationship S≦W/2, the influence of a potential attributed to an abnormal charge which concentrates on the end portion of the data signal line spreads radially and does not extend to a center portion of the divided portion thus suppressing an abnormal discharge.
