Spacers are fixed on scanning signal lines by a bonding member and conductive bonding member. Since the scanning signal lines and the spacers formed on a back substrate are fixed with the bonding member and the conductive bonding member, electrostatic charge of the spacers can be prevented. According to the invention, a display device which can obtain an image display with a high white uniformity is provided by stabilizing the potential applied to spacers and stabilizing the beam landing of electron beams.
