PCT No. PCT/JP96/02814 Sec. 371 Date Jul. 21, 1997 Sec. 102(e) Date Jul. 21, 1997 PCT Filed Sep. 27, 1996 PCT Pub. No. WO97/12277 PCT Pub. Date Apr. 3, 1997The invention provides a display device which improves the shape of the contact region while increasing yield and reducing product cost. A contact region is a region between signal lines, and is a region following a scan line so as to include either a part of or an entire of the pixel electrode edge region following the scan line connected to the switching element. The pixel electrode is connected to the source electrode in this region. The contact hole may be rectangular, and a plurality of contact holes may be provided. Also, if CX is the parasitic capacitance between the pixel electrode and the source electrode when a bad contact exists between said pixel electrode, C0MAX is the maximum value of the pixel capacitance held by the pixel electrode when said bad contact does not exist, VLCMIN is the voltage when the transmissivity at a pixel position is a minimum, and VLCMAX is the voltage when the transmissivity is a maximum, a capacitance ratio RAC1 is set such that the following relationship is established: RAC1=CX/C0MAX>VLCMAX/(VLCMIN-VLCMAX). The invention thereby apparently eliminates a pixel defect of a bad contact.
