PROBLEM TO BE SOLVED: To provide a high-quality image display device by setting a uniform low resistance with a uniform film thickness over the entire length of a scanning line electrode, and suppressing local resistance unevenness and disconnection of the scanning line electrode. A scanning line lower electrode GL-L, a first insulating layer INS1, a signal line electrode DL, a second insulating layer INS2, embedded in a groove MZ in which a main surface of an insulating substrate SUB1 serving as a first substrate is processed, A stacked structure of the third insulating layer INS3 and the scanning line upper electrode GL-H is employed. The electron source EM includes the signal line electrode DL, the second insulating layer INS2, and the scanning line upper electrode GL-H. [Selection] Figure 4 |
