Abstract

PURPOSE:To perform a readable and obvious display by changing colors to be displayed of display information, by forming the liquid crystal display device in the form of multilayer to enclose different-color transmission type liquid crystals into each layer and by establishing a white-colored diffusing plate on the back of the display device to drive the device selectively. CONSTITUTION:The liquid crystal display device is formed in two layers or more, between the upper glass substrates 2, 3, for example, a nagative type blue-colored GH liquid crystal 6 is enclosed and between the lower glass substrate 3, 4 a red- colored GH liquid crystal 7 is enclosed. Further at the outside of a glass substrate 4, a white-colored diffusion plate 12 to permit external light to diffuse and to transmit from the rear is arranged. In this mechanism, by selecting properly application of voltage to transparent electrodes 8, 9 in the first layer and transparent electrodes 10, 11 in the second layer to drive a display path in each layer, three kinds of different display colores such as white, blue and red are obtained. Therefore, in composite electronic devices, etc. the displayed color of information can be changed according to the different functions (a function for calculation, water, calender and others).
