Abstract
There is provided a display unit capable of reducing deterioration in the 3D characteristics. A phase difference device is bonded to a surface on a light outgoing side of a liquid crystal display panel. In the phase difference device, two kinds of phase difference regions with slow-axis directions different from each other are arranged in correspondence with each pixel. Each of the phase difference regions is arranged in contact with the phase difference region of a different kind, and a side section, of each of the phase difference region, that is in contact with the phase difference region of the different kind has waviness with an amplitude a that satisfies following expressions:0<max(φ)max(φ)=−0.7/(φ−1.2)+0.35φ=arctan(/(4))
