The present invention provides a reflective-type liquid crystal display device with a reflection electrode thereof formed on a resin binder layer wherein a number of fine particles are mingled in the resin binder layer and protrude their upper portions from the resin binder layer to make an upper surface of the resin binder layer rough, and improves reflection property thereof while simplifying a structure and manufacturing process therefor.

Reflective-type liquid crystal display device including resin layer with fine particles

In a liquid crystal display device comprising color filters therein, the present invention provides a color-converting material in at least one of the color filters which converts a part of an incident light of the at least one of the color filters into a light in a specific wavalength range together with a filter material passing the light in the specific wavelength range, so as to prevent deterioration of color purity of the light emitted thereby and to improve efficiency of optical utilization therein.
