Abstract
An anti-reflective integrated touch display panel includes an anti-reflective structure and touch electrodes. The anti-reflective structure includes a first insulating layer, a second insulating layer disposed on the first insulating layer, a conducting layer disposed on the second insulating layer, a third insulating layer disposed on the second insulating layer, and a fourth insulating layer disposed on the third insulating layer. The first insulating layer includes silicon oxide or silicon nitride, and has a thickness of 0.1 to 2 micrometers. The second insulating layer includes silicon oxide or strontium oxide, and has a thickness of 0.001 to 0.1 micrometer. The conducting layer includes molybdenum, and has a thickness of 0.01 to 0.05 micrometer. The fourth insulating layer includes silicon nitride, and has a thickness of 0.001 to 0.3 micrometer. The touch electrodes are disposed between the third insulating layer and the fourth insulating layer.
