In the configuration of the current liquid crystal display for example, the back light module is in charge mainly of providing back light . The liquid crystal panel is in charge mainly of controlling whether the back light passes through to generate required color light for each pixel. The structural frame is in charge of connecting, supporting, and fixing related or close disposed components. The appearance decoration part is in charge of providing an appearance visual effect for the whole apparatus. The modular design is contributive to simplifying product design and increase reuse rate of design, but the amount of the components is hard to be reduced leading to difficulty in reducing product volume. Furthermore, the assembly of the components usually unavoidably involve seam or step therebetween so that the product appearance hardly provides a visual effect of integral whole to users.

Thestructural frame 14 has aside surface 14 a. Thesecond edge 104 a of thesecond substrate 104 of the displayingpanel 10 is aligned with theside surface 14 a. - In the embodiment, the displaying
panel 10 is a liquid crystal panel. Theoptical filter structure 106 is used for produce different color lights, such as red light, green light, and blue light. Thelight modulation units 110 are realized on the basis of light penetration mechanism of liquid crystal; however, the invention is not limited thereto. In the embodiment, theoptical filter structure 106 is formed on thesecond substrate 104. The light-maskingstructure 108 is the black matrix for the liquid crystal panel and is also formed on thesecond substrate 104 capable of dividing theoptical filter structure 106 into a plurality of color areas. In logic, thelight modulation unit 110 includes twoelectrodes first substrate 102 and thesecond substrate 104 respectively, aliquid crystal 1104 disposed between theelectrodes semiconductor switch 1106 formed on thefirst substrate 102 and electrically connected to theelectrodes electrodes 1102 b are taken as a single common electrode. Theelectrodes 1102 a and the semiconductor switches 1106 are realized by forming a thin-film-transistor matrix on thefirst substrate 102. Theelectrodes 1102 a function as cell electrodes and are controlled by corresponding semiconductor switches 1106. Theliquid crystal 1104 is filled between thefirst substrate 102 and thesecond substrate 104. Spacers are involved to maintain a distance between thefirst substrate 102 and thesecond substrate 104.
