Claim:
1. A display device comprising: a grayscale conversion portion; and a display portion including a plurality of pixels provided at a resolution of 80 ppi or more, one of the plurality of pixels comprising a light-emitting module capable of emitting light with a spectral line having a peak in which a half width of the peak is 60 nm or less and a transistor including an oxide semiconductor, wherein the light-emitting module includes an organic EL element and a color filter, wherein the grayscale conversion portion is configured to convert a first image signal inputted to the grayscale conversion portion into a second image signal and transmit the second image signal to the display portion, wherein the first image signal has p gray levels (p is a natural number and an even number), wherein the second image signal is subjected to a grayscale conversion processing in which each of q gray levels from the lowest gray level to the q-th gray level is further divided into 2 wherein q is greater than or equal to 1 and less than or equal to p/2 and r is greater than or equal to 1 and less than or equal to 20.
