At the same time, a small amount of coloring matter to added to the liquid crystal material to make even the background part of display. Thus a black display is given on the white background to obtain a twisted nematic type liquid crystal display element. The coloring matter which has good dissolving performance to the liquid crystal material with even mixture is usable. In case a coloring matter which is used to a guest-host type liquid crystal display element, etc. is used, an easier-to-see display is secured since the effect of the coloring matter is substantially eliminated for the black display at the glowing part.
