ABSTRACT:
A wide line portion is drawn from a cathode while another wide line portion is formed by gathered lines extending from cathode terminals. A contact of realtively large size is formed in a region where the two wide line portions overlap each other with an insulating film being interposed therebetween, so as to connect both wide line portions. Further, in this contact, the cathode terminals and the cathode are connected through an intermediate layer composed of a conductive oxide material. Thus, a reduction in the voltage to be applied to the cathode as a result of increased line resistance between the terminals and the cathode can be prevented, thereby preventing deterioration of display quality.
