A thin film transistor array panel includes a substrate, a first thin film transistor formed on the substrate, a color filter formed on the first thin film transistor and having a through hole, a capping layer formed on the color filter and having an opening, and a pixel electrode formed on the capping layer and connected to the first thin film transistor through the through hole. The first randomly repeating monomer unit has the structure, wherein R1 is H, or C1 or C2 alkyl, and n is 1 or 2. The first area having the reflecting film partly removed includes a portion which is formed by removing the reflecting film, and has a length longer than a maximum pit length determined by the modulation method in a circumferential direction of the optical disk. This information may be provided via direct detection of the signal by an operator of the apparatus. The measured distance value may be obtained by measuring the quality factor of the resonator or accelerometer and deriving the measured distance value from the quality factor measurement. , to enable formation relatively thin andor flexible footwear sole components.
