A regenerative relay method includes the steps of: i) calculating an error rate of a transmission path between the first half apparatus and a main apparatus; ii) calculating an error rate of a transmission path between the main apparatus and the latter apparatus; iii) adding the error rates; iv) selecting the error correction code and data before the error is corrected in the main apparatus so as to be supplied to the latter apparatus if the added error rates are lower than a designated error correction threshold; and v) selecting data after the error is corrected in the main apparatus and the other error correction code generated from the data so as to be supplied to the latter apparatus if the added error rates are higher than the designated error correction threshold.

In a liquid crystal display (10) having a curved display surface, long sides of pixel structures (11) are arranged along the curve direction (Y) of the display surface and on a side of counter substrate provided is a black matrix having a black matrix opening (41a) whose length in the curve direction (Y) is not longer than E−L {(T1/2)+(T2/2)+d}/R, assuming that the length of the display surface in the curve direction (Y) is L, the thickness of an array substrate is T1, the thickness of the counter substrate is T2, the size of the gap between the array substrate and the counter substrate is d, the radius of curvature of the curved display surface is R and the length of a long side of a pixel electrode (29) provided in each of the pixel structures (11) is E. It thereby becomes possible to suppress display unevenness resulting from positional misalignment of the two substrates due to curvature and provide a liquid crystal display achieving a high-quality display image.

A method of manufacturing a thin-film transistor according to an embodiment of the present invention includes the step of forming a gate insulator on a gate electrode. The gate insulator includes at least a first region being in contact with a hydrogenated amorphous silicon film, and a second region positioned below the first region. The first and second regions are deposited using a source gas including NH3, N2, and SiH4, and H2 gas or a mixture of H2 and He. The first region is deposited by setting the flow-rate ratio NH3/SiH4 in a range from 11 to 14 and the second region is deposited by setting the flow-rate ratio NH3/SiH4 to be equal to or less than 4. It is thus possible to provide a thin-film transistor having excellent characteristics and high reliability, a method of manufacturing the same, and a display device including the thin-film transistor mounted thereon.

The optical transmitter and receiver of the invention includes: a variable dispersion compensator that performs wavelength dispersion compensation on an optical signal of a differential M-phase modulation format input from a transmission path; an optical amplifier that compensates an optical loss in the variable dispersion compensator; a delay interferometer that delays and interference processes the optical signal output from the optical amplifier; and a photoelectric conversion circuit that photoelectric converts the output light from the delay interferometer to generate a demodulated electric signal. The output level of the optical amplifier is decreased at the time of start up to deteriorate the OSNR of the optical signal input to the photoelectric conversion circuit, to thereby realize a state in which an error occurs more easily, and then optimization control of the variable dispersion compensator and the delay interferometer is started. As a result optimization of the dispersion compensation amount and the phase control amount in the optical receiver corresponding to the differential M-phase modulation format can be performed in a short time.
