Abstract
PURPOSE: To secure the suitable color display for the TV signals even with use of the liquid crystal by enabling the black display and the luminance adjustment through combination of the 3-color display picture elements and a linear polarizing display layer.
CONSTITUTION: The picture element unit is formed by aligning red polarizing plate mask 18, blue polarizing plate mask 19, green polarizing plate mask 20 and linear polarizing plate mask 21 each. In other words, figures 22, 23, 24 and 25 show the red, blue, green and black picture element being added to the normal electrodes. In such constitution, in case no signal enters the picture elements of red, blue and green each, the voltage is applied to the picture element of 25 corresponding to the linear polarizing plate to perform the display of black. As a result, the dark display is given with the four picture elements as a whole. Furthermore, the black picture element is used for adjustment of the luminance.
