322 324 326 and 328 include the parallel slits 342 344 346 348 350 352 354 356 358 360 362 and 364 the fence regions 318 320 322 324 326 and 328 influence the light 366 by an interference effect a first exposure energy acting on the main regions 312 314 and 316 of the address electrodes is greater than a second exposure energy acting on the edge regions 330 332 334 336 338 and 340 of the address electrodes as shown in fig1 after the exposure process a development process is performed to develop the photosensitive conductive paste film 302 to form the address electrodes 368 370 and 372 since the second exposure energy acting on the edge regions 330 332 334 336 338 and 340 of the address electrodes 368 370 and 372 is less than the first exposure energy acting on the main regions 312 314 and 316 of the address electrodes 368 370 and 372 a first thickness of the edge regions 330 332 334 336 338 and 340 of the address electrodes 368 370 and 372 is less than a second thickness of the main regions 312 314 and 316 of the address electrodes 368 370 and 372 as shown in fig1 a firing process is.
