    • An LCD comprises: an upper array substrate and a lower color filter substrate, which are opposed and spaced a predetermined distance to each other; a reflective film formed in a matrix on a non-pixel section on the color filter substrate; a black-matrix formed on the reflective film; red, green, and blue color filters, formed on pixel sections of the color filter substrate defined by the black-matrix; a lower orientation film formed on the whole area of substrates including the color filters and black-matrix; a pixel electrode formed on the pixel section on the array substrate; an upper orientation film formed on the whole area of substrates including the pixel electrode; a liquid crystal layer interposed between the color filter substrate and the array substrate; a partially masked lower polarizer mounted outside the color filter substrate, in which a portion under the non-pixel section does not have polarization function; and an upper polarizer mounted outside the array substrate. In the LCD, light absorbed in black-matrix is utilized by positioning the color filter substrate at a lower portion thereof and mounting the reflective film under black-matrix. The partially masked polarizer is used as the lower polarizer so as to minimize optical loss by black-matrix and polarizer, thus improving optical efficiency.
    • LCD包括:上阵列基板和下彩色滤光片基板,彼此相对且隔开预定距离; 反射膜,其形成在滤色器基板上的非像素部分上的矩阵中; 形成在反射膜上的黑矩阵; 红色,绿色和蓝色滤色器,形成在由黑矩阵限定的滤色器基板的像素部分上; 形成在包括滤色器和黑矩阵的基板的整个区域上的下取向膜; 形成在阵列基板上的像素部分上的像素电极; 形成在包括像素电极的基板的整个区域上的上取向膜; 插入在滤色器基板和阵列基板之间的液晶层; 安装在滤色器基板外部的部分掩模的下偏振片,其中非像素部分下方的部分不具有偏振功能; 以及安装在阵列基板外部的上偏振器。 在LCD中,通过将滤色器基板定位在其下部并将反射膜安装在黑矩阵下,可以利用黑矩阵吸收的光。 部分掩模的偏振器用作下偏振器,以便通过黑矩阵和偏振器使光学损耗最小化,从而提高光学效率。
