At pole 17, the emitted light color is green. If the green light emission intensity is made sufficiently lower than the orange light emission intensity, the background will become a green light emission color, and the display patterns such as letters and numbers 0 will become an orange light emission color. Therefore, the display pattern appears to stand out, and the quality of the display is improved. In particular, when the surroundings are dark, the display pattern can be made clearer. (B) Lower electrode 14 and upper 'FIfl15 of thin film electroluminescent surface 10

Since the pattern can be displayed in any of the nine luminescent colors of the i-type electroluminescent surface 10 and the luminescent colors of the dispersion type electroluminescent surface 11, it is possible to display the pattern in two colors. Furthermore, if the overlapping positions are made to emit light at the same time, the composite color of the two emitted light colors becomes the emitted color, and it is possible to display in three colors.
