A display device includes a substrate (), pixel electrodes (PIX) formed on the substrate (), scanning lines (G) to transmit scanning signals, signal lines (S) divided into four groups (LL, LR, RL and RR) to transmit data signals, signal line driving circuits () to drive the groups (LL, LR, RL and RR) of the signal lines (S), respectively, analog switch control signal lines (and) connected between the signal line driving circuits () and the groups (LL, LR, RL and RR) of the signal lines (S), and transistors (ASW) connected between the analog switch control signal lines (and) and the groups (LL, LR, RL and RR) of the signal lines (S) to provide the data signals to the pixel electrodes (PIX) in response to the scanning signals. An electrical path length between the signal line driving circuits () and a point (A) of the analog switch control signal lines (and) provided at a boundary region between the groups (LL and LR), for example, of the signal lines (S) is configured to be substantially the same as the one between the signal line driving circuits () and a point (B) of the analog switch control signal lines (and) provided at a boundary region between the groups (LL and LR) of the signal lines (S).

Display device

A liquid crystal layer is sealed between an array substrate and an opposed substrate arranged to oppose each other with a gap. A multiplicity of particulate spacers are arranged between the array and opposed substrates to maintain the gap therebetween. The array substrate is formed with a transparent insulating film covering signal lines, scanning lines, switching elements and pixel electrodes. The areas of the insulating film opposing the respective pixel electrodes are each formed with a plurality of apertures for limiting the movement of the spacers.
