A touch apparatus includes first touch electrodes and second touch electrodes. The first touch electrodes and the second touch electrodes are interlaced, so as to define first interlaced regions. Each of the first touch electrodes includes first main portions extended in a first direction and second main portions extended in a second direction. The first main portions and the second main portions are crossed, so as to form first grids. Each of the first touch electrodes further includes first branches crossed with two segments of two adjacent first main portions of at least one of the first grids.
