Abstract

A color filter includes a substrate and a plurality of pixel units. The substrate defines a plurality of pixel areas. Each pixel area has a plurality of first sub-pixel areas, and each first sub-pixel area has a first area and a second area. The pixel units are formed on the substrate corresponding to the pixel areas. Each pixel unit is disposed in a corresponding pixel area and includes a plurality of color subtractive filter films and a plurality of color additive filter films. The color subtractive filter films are disposed in the first areas of the first sub-pixel areas of the corresponding pixel area, and the color additive filter films are disposed in the second areas of the first sub-pixel areas of the corresponding pixel area. A color display device with the color filter is also disclosed. The color filter of the invention enhances the display brightness of the color display device and the color saturation during the display.

Description

technical field [0001] The invention relates to a color filter, and in particular to a color filter with high transmittance and a color display device using the same. Background technique [0002] A reflective display uses reflected incident light as a light source for displaying images on the display. With the demand of consumers for products, the requirements of colorful and thin and light also arise at the historic moment. [0003] In the display, the color filter is a key component of color performance. figure 1 It is a schematic cross-sectional view of an existing color reflective display. Please refer to figure 1 , the color reflective display 100 includes a color filter 102 , a display medium layer 104 and an active element array substrate 106 . The light L outside the color reflective display 100 passes through the color filter 102 and the display medium layer 104 in sequence, and then is reflected by the active element array substrate 106 to pass through the dis...
