The light emission region is composed of linear light emission regions extending in the direction orthogonal to the vertical scan direction of liquid crystal.

The linear light emission regions are controlled so as to be in the non-light-emitting state at least in a time period where drive data of that portion of the liquid crystal which is directly above the linear light emission regions are being rewritten. | ||||||
