A display method is provided that reduces the probability of communication error without causing significant deterioration of picture quality. The method includes specifying, as a specified light emission period, a light emission period in which light emission is performed for greater than or equal to a time required for transmitting a block included in a visible light communication signal, out of one or more light emission periods in which light emission is performed for displaying an image included in a video signal. The method also includes transmitting the block of the visible light communication signal by luminance changing in the specified light emission period.
