Display unit and display method

A display apparatus for providing a grayscale display based on a video signal with a grayscale level using a sub-field method, comprising:

• a display panel that is composed of a plurality of areas each including first, second, third, and fourth pixels that are vertically and horizontally adjacent to one another;
• and
• a grayscale display unit that stores first, second, third, and fourth tables that include a plurality of first, second, third, and fourth emission patterns corresponding to said respective first, second, third, and fourth pixels in each area, and selects first, second, third, and fourth emission patterns corresponding to said first, second, third, and fourth pixels, respectively, from said first, second, third, and fourth tables based on the grayscale level of the video signal, so as to provide a grayscale display by causing said first, second, third, and fourth pixels in each area of said display panel to emit light or not for each sub-field based on the selected first, second, third, and fourth emission patterns, wherein
• combination patterns of emissions and non-emissions in predetermined sub-fields of said plurality of sub-fields are different among said first, second, third, and fourth emission patterns,
• said first pixel and said second pixel are arranged in one diagonal positions while said third pixel and said fourth pixel are arranged in another diagonal positions in each area, and
• for each grayscale level, a grayscale value represented by each of said first emission pattern and said second emission pattern is lower than an average of grayscale values represented by said first, second, third, and fourth emission patterns, while a grayscale value represented by each of said third emission pattern and said fourth emission pattern is higher than said average.
