Abstract

PURPOSE: To obtain threshold values visually, by using an electro-optical modulating material not having a threshold value for making the front electrode provided in a front substrate for display non-transparent.
CONSTITUTION: When composing a transmission type display device 11 by fitting front and rear electrodes 12, 12', 14 to front and rear substrates 13, 15 for display made of transparent and insulating glass material or the like and sealing with an electro-optical modulating material 16, the front electrodes 12, 12' are made of opaque material such as aluminum. When the applied voltage to the electro-optical modulating material 16 such as quinine sulfate iodide is 0, even if the light transmissivity is nearly 0, there is not threshold value with respect to the transmissivity, and when a certain voltage is applied to electrodes 12, 12', an electric leak field is generated in the crosswise direction, so that the transmissivity of the electro-optical modulating material 16 increases in a wider range than the form of the front electrodes 12, 12'. Thus, numeric figures are displayed by the transparent part 18 of this material 16 and bulging front electrodes 12, 12'. Therefore, numerals may be identified when a certain voltage is applied, so that visual threshold values may be obtained.
