Ultraviolet photoemission spectra of high-Tc superconductor (La1-xSrx)2CuO4-δ, (x=0.075 and δ≦0.04) are presented. The experimental result was compared with the band calculations of La2CuO4 by Mattheiss and Takegahara et al. It was found that as regards the valence-band width (about 7 eV) the experiment and the calculations are in good agreement with each other, but the position of the calculated valence bands contributed mainly by weakly bonding Cu(3d)-O(2p) states are shiftd toward the lower binding energy by about 1 eV with respect to the experiment. The possible origins for this discrepancy were discussed.
