The first mask structure is disposed on a surface of the substrate and divides the substrate into a mask area and a visible area disposed adjacent to the mask area. The first mask structure is disposed in the mask area. The dense structure at least masks a surface of the first mask structure farther from the substrate.

A continuous preparation method of a biodegradable aliphatic / aromatic polyester copolymer includes: performing a first esterification reaction of an aliphatic dihydroxy compound with an aliphatic dicarboxylic acid at a temperature of 185° C. or less; continuously performing a second esterification reaction of a reaction product from the first esterification reaction; continuously performing a first polycondensation reaction of a reaction product from the second esterification reaction to obtain a prepolymer having a weight average molecular weight of about 6,900 to about 14,000; continuously performing a second polycondensation reaction of the prepolymer to obtain a second polycondensation reaction product; and continuously performing a third polycondensation reaction of the second polycondensation reaction product to prepare the biodegradable aliphatic / aromatic polyester copolymer, wherein the performing of the first esterification reaction or the continuously performing of the second esterification reaction includes adding an aromatic carboxylic acid. The biodegradable aliphatic / aromatic polyester copolymer prepared by the continuous method may be improved in processibility, film formability, tensile / tearing strength, and blending ability with another polymer resin. Use of a less amount of the aliphatic dihydroxy compound as a starting material may reduce manufacturing costs.

The image signal converting apparatus is used in a lighting unit. The lighting unit includes a liquid crystal panel modulating a red component light according to a red image signal, a liquid crystal panel modulating a green component light according to a green image signal, and a liquid crystal panel modulating a blue component light according to a blue image signal. Yellow component light is superimposed on any of the red component light, the green component light and the blue component light. The image signal converting apparatus includes a controlling unit which controls a superimposition amount of yellow component light based on a specific image signal among a red image signal, a green image signal, and a blue image signal. A color corresponding to the specific image signal has a hue adjacent to a hue corresponding to the yellow component light. The controlling unit controls a reduction amount of the specific image signal based on the superimposition amount.

An aqueous solution for treatment of colored concrete, glazed enamel or porcelain surfaces to increase the coefficient of friction of that surface, whether dry or wet, to about 0.8 without deteriorating the color of the surface comprises about 1.5 to 1.9 wt % of ammonium bifluoride, 1.5 to 3.0 wt % of tri-ethylamine and a wetting agent in water. The degree of change of the color of the surface, treated seven minutes with the solution of the current application, measured by a color meter shows only 0.56 while the result of a commercial solution to increase the frictional coefficient shows 2.22. This means that the color change by the solution of the current application is undetectable by human eyes. Meanwhile, the change by the commercial solution product is detectable.
