Abstract: A color filter substrate includes a transparent substrate, a number of color photoresists disposed on the transparent substrate and a high-reflecting region disposed on the transparent substrate. The high-reflecting region at least includes a first region for separating the color photoresists. The high-reflecting region either is filled with a reflecting material or is empty. A display device is also provided. The display device includes a lower substrate, a driving circuit layer disposed on the lower substrate, a display layer disposed on the driving circuit layer and the above-mentioned color filter substrate disposed on the display layer. The color filter substrate can be assembled to the display device to increase the total light intensity of light reflection, thereby improving the display quality of the display device.
