发明名称 COLOR LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURE THEREOF
摘要 <p>PURPOSE: To make the contrast of a display picture high and to make a light-shielding layer thin by providing a color filter formed at a position corresponding to a chromatic color picture element and a translucent filter formed in the vicinity of the outer periphery of the position corresponding to an achromatic color picture element and the position corresponding to a picture element where the color filter is formed. CONSTITUTION: Only the filters 12, 14 and 16 of respective colors are formed on a side a little inside from the position corresponding to a picture element electrode 6 formed on a glass substrate 2 at the filter layers 9 of red, green and blue picture elements 13, 15 and 17, namely chromatic picture elements, and the translucent filter 18 and the filters 12, 14 and 16 of the respective colors are laminated at an outside position than a little inside from the position corresponding to the picture element electrode 6 formed on the position other than that, namely on the glass substrate 2. The filter layer 9 of the achromatic picture element 19 having the translucent filter 18 is constituted by laminating the translucent filter 18 and transparent material 20. Also, the light-shielding layer 21 is formed by laminating the filters 12, 14 and 16 of the respective colors and the translucent filter 18. Thus, high contrast is obtained and the light-shielding layer is made thin.</p>
