Abstract

PURPOSE:To obtain a liquid crystal display element for color display, which is capable of clearly displaying a fine image without any color shift due to parallax, by low applied voltage. CONSTITUTION:On a transparent substrate 1, a colored polarized film 2 consisting of regular stripe patterns of red, green and blue, having fine width is formed, and on said film, a protective transparent thin film 3 and a transparent electrode 4 are formed in order. Also, picture element electrodes E11, E12... are provided so as to be opposed, by placing a liquid crystal layer 6 and orientation layers 5, 7. Since only the orientation layer and the liquid crystal layer exist between the electrodes, applied voltage can be lowered, also, since thin film transistors T11, T12 for a switch are provided so as to be connected to the picture element elec trodes E11, E12..., respectively, there is no crosstalk, and also, each color of each picture element electrode and the colored polarized film 2 are matched and placed, and a space between both of them is narrow, therefore, the clear color display which is small in parallax and has no color shift can be executed.

。以下本発明分その実施例ケ示す図面に基き詳述する。Liquid crystal display elements capable of color display are being actively developed, and various proposals have been made to improve the clarity and resolution of displayed images. The multicolor liquid crystal display device disclosed in JP-A No. 56-21182 has little color shift and is capable of displaying fine patterns by forming a colored light-transmitting film on the transparent electrode or at least on the surface of the substrate containing the transparent electrode. However, because the above-mentioned colored light-transmissive film (i.e. color) is interposed between the electrodes that are placed opposite to each other with the liquid crystal in between, the voltage applied between the electrodes is A portion will be applied to the color filter layer. For this reason, the transmittance-voltage applied between the electrodes characteristic of the liquid crystal becomes slow (the amount of change in transmittance with respect to unit voltage change t is small), that is, the driving characteristics are poor, and in order to obtain a clear display 1, the applied voltage must be high. It becomes necessary to do so. However, when performing matrix display, there is a problem in that when a high voltage EE1 is applied to T/c, the effect appears on adjacent parts, making the image unclear.
If the color filter layer is made thinner in order to avoid this problem, sufficient color density will not be obtained. An object of the present invention is to provide a liquid crystal display element for color display that can display clearly without color shift due to parallax. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to drawings showing embodiments thereof.
