ABSTRACT:
A touch panel including a first substrate, a second substrate, a sealant, a liquid crystal layer, a main spacer, a first sensing spacer, a second sensing spacer, a first opposite electrode and a second opposite electrode is provided. The first substrate has a central area and a peripheral area. The second substrate is disposed opposite to the first substrate. The first sensing spacer is disposed on the central area and between the first and the second substrates. The second sensing spacer is disposed on the peripheral area and between the first and the second substrates. There's a first sensing gap between the first sensing spacer and the first opposite electrode disposed corresponding to the first sensing spacer. There's a second sensing gap between the second sensing spacer and the second opposite electrode disposed corresponding to the second sensing spacer. The first sensing gap is larger than the second sensing gap.
