PROBLEM TO BE SOLVED: To reduce flickers occurring in cyclical picture signal display and non-picture signal display. SOLUTION: The liquid crystal display comprises a plurality of liquid crystal pixels PX; a vertical drive circuit YD for selecting the line of the pixels PX for either picture signal write and for non-picture signal write; a horizontal drive circuit XD for writing a picture signal to the pixel PX of the line selected for the picture signal write and writing a non-picture signal to the pixel PX of the line selected for the non-picture signal write; and a controller 5 for controlling the horizontal drive circuit XD and the vertical drive circuit YD so as to write the picture signal to the plurality of pixels PX line by line, sequentially in one vertical scanning period, and write the non-picture signal to the plurality of pixels PX at least line by line sequentially, delayed from the first write of the picture signal by a time shorter than the vertical scanning period. The vertical drive circuit YD in particular sets a selection pattern, in which the selection period for writing the picture signal with respect to the pixel PX of each line does not coincide with the selection period for writing the non-picture signal to the pixel PX of the other lines, based on enable signals OE1-OE3 provided from the controller 5.
