A display device includes a visible light reflecting layer and a fluorescent layer. The visible light reflecting layer transmits an invisible light. The visible light is reflected from the visible light reflecting layer. The fluorescent layer is on the visible light reflecting layer to generate a visible light in response to the invisible light that has passed through the visible light reflecting layer. The fluorescent layer transmits the visible light reflected from the visible light reflecting layer. Therefore, a manufacturing cost is decreased, and an efficiency of light is improved.

The present invention relates to a chemical mechanical polishing (CMP) pad with a micro-mold, and a production method thereof. More particularly, the present invention relates to a CMP pad with a micro-mold, in which the surface of the CMP pad is uniformly formed so as to avoid the glazing of the polishing pad, prevent a change in slurry flow and maintain the contact area between the polishing pad and a semiconductor wafer constant, thus allowing the wafer to be polished in a continuous and stable manner, and permitting the semiconductor wafer to be polished into the desired shape, as well as a production method thereof.
