We demonstrate a production of large-area $^{87}$Rb Bose-Einstein condensates(BECs) using a non-Gaussian optical dipole trap (ODT). The ODT is formed byfocusing a symmetrically truncated Gaussian laser beam and it is shown that thebeam clipping causes the trap geometry elongated and flattened along the beamaxis direction. In the clipped-Gaussian ODT, an elongated, highly oblate BEC of$^{87}$Rb is generated with length and width of approximately$470~\mu\textrm{m}$ and $130~\mu\textrm{m}$, respectively, where the condensatehealing length is estimated to be $\xi\approx 0.25~\mu\textrm{m}$ at the trapcenter. The ODT is characterized to have a quartic trapping potential along thebeam axis and the atom density of the condensate is uniform within 10% over$1000\xi$ in the central region. Finally, we discuss the prospect of conductingvortex shedding experiments using the elongated condensate.
