摘要:
A display device includes a multiplicity of pixels arranged in a matrix of rows and columns, each pixel including a plurality of color pixels each divided into a plurality of sub-color pixels having mutually different areas. The plurality of sub-color pixels are arranged in the row or column direction in different manners for at least two of said plurality of color pixels. As a result, the sub-color pixels may be arranged so that, when the respective color pixels are driven to display an identical gradation level, a ratio of a row-direction line width to a column-direction line width is closer to 1 than the ratio obtained when all the color pixels have an identical sub-color pixel arrangement, whereby numerals and characters, for example, can be displayed at an improved display quality.
