摘要： An image signal processing apparatus performs gradation control on respective pixels. Specifically, the image signal processing apparatus includes an image signal processing unit which controls light emission and non-light emission of respective subfields so as to provide a field having a level of brightness. Here, the field is a unit display period of the pixels and divided into the subfields which have different light emission periods and are arranged in a predetermined sequence. In the predetermined sequence, the subfields are arranged in a manner such that a subfield having the shortest light emission period among the subfields is in the first place, one of a subfield having the longest light emission period and a subfield having the second longest light emission period among the subfields is in the second place, and the other one is in the third place.
