A display apparatus is disclosed, and comprises a display panel and a lens. On the display panel, there are a width-fixed pixel zone, a width-variating pixel zone and a border zone arranged sequentially from the center to the edges of the display panel, wherein there are a plurality of width-fixed pixels disposed in the width-fixed zone, and there are a plurality of width-variating pixel groups disposed in the width-variating pixel zone, and the widths of the width-variating pixel groups are present in a first decreasing sequence. The lens has a focus-length-variating portion and a planar portion, wherein the planar portion is aligned with the width-fixed pixel zone, and the focus-length-variating portion is disposed to correspond to the border zone and the width-variating pixel zone. The focus lengths of the focus-length-variating portion corresponding to the width-variating pixel groups are present in a second decreasing sequence.
