Abstract

Embodiments relate to a defect detecting method of a line (L1) and a demultiplexer (200), a defect detecting device (100), and a display panel including the defect detecting device (100). A demultiplexer (200) may connect a plurality of data lines (D1, D2, ..., Dm) to a plurality of corresponding lines (L1, L2,..., Lk). The defect detecting device includes DC lines (DC_R, DC_G, DC_B) supplied with respective DC voltages, first switches (T11, T12, ..., T1a) connected to the DC lines (DC_R, DC_G, DC_B) and configured to transmit the respective DC voltages to the corresponding first data lines (D1, D2, D3, D7, D8, D9) among a plurality of data lines (D1, D2, ..., Dm) according to a first gate signal, and second switches (T21, T22,..., T2b) connected to the first to third DC lines (DC_R, DC_G, DC_B) and configured to transmit one of the respective DC voltages to corresponding second data lines (D4, D5, D6, Dm-5, Dm-4, Dm-3) among a plurality of data lines (D1, D2, ..., Dm) according to a second gate signal.
