The present invention provides a transflective display device which is high in transmittance, can secure sufficient brightness in display, and can display black. A transflective display device 1 includes a display panel 2 and a backlight 3. The display panel 2 includes a substrate 10 having an electrode 12. a substrate 20 having an electrode 22, and an optical modulation layer 30 containing shape-anisotropic members 32. A frequency of a voltage to be applied to the electrodes 12 and 22 is changed so as to rotate the shape-anisotropic members 32. When the shape-anisotropic members 32 are oriented such that their major axes extend in parallel with one of the substrates on which the shape-anisotropic members 32 abut, multiple reflection of incoming light is caused, and thus black is displayed.
