This article describes new Color Filter of LCD by·makeing use of the light interference m This disclosed method put a new Color Filter into practice by light interference of ITO me Different thickness ITO membrane makes different wavelength light of interference. It makes possible to separate the light to three color lights of RGB spectrum. This disclosed method makes RGB of Color Filter by different color light of interference b The LCD cell process is contain ITO construct process, So this LCD cell process is using the process of making different thickness ITO, We can make this ITO Color Filter and the Cell at the same time in the same process. In the case of conventional technology we use color paint in each RGB pixel. This disclosed technology reduces patterning process in Color Filter manufacturing, then it can reduce some manufacturing process and cost. The Figures show an example of design. Fig-1 shows the conventional design of Color Filter .
