When a sub-pixel of B having a small contribution to luminance emits light in isolation, a sub-pixel of R is caused to emit light or sub-pixels of B and R are caused to emit light. As a result, a sub-pixel of R having, a larger contribution to luminance than the sub-pixel of B, is caused to emit light. When an adjacent set of sub-pixels B and R having a small contribution to luminance emits light in isolation, a set of sub-pixels R and G is caused to emit light. As a result, a set of sub-pixels R and G having a higher degree of contribution to luminance than the set of sub-pixels B and R is caused to emit light. Therefore, contrast degradation from any allocation of light-emitting patterns to sub-pixels having poor luminance is eliminated and a high quality display is achieved.
