A liquid crystal display device includes: an active matrix substrate with a pixel electrode in each of a plurality of pixels; a counter substrate including a counter electrode that opposes the pixel electrode; a liquid crystal layer between the active matrix substrate and the counter substrate; and a pair of polarizers oppose each other via the liquid crystal layer and are in a crossed Nicols arrangement. The pixel electrode- includes a cruciform trunk portion arranged to coincide with polarization axes of the polarizers, a plurality of branch portions extending from the trunk portion, and a plurality of slits between the branch portions. The active matrix substrate further includes an auxiliary electrode which is arranged to oppose the pixel electrode via an insulation layer. The auxiliary electrode and the pixel electrode define a storage capacitor.
