ABSTRACT:
A liquid crystal display apparatus includes a first substrate, a second substrate having a counter electrode, and a liquid crystal layer sandwiched between the first substrate and the second substrates. The first substrate includes: a plurality of pixel electrodes arranged in a matrix; a plurality of source bus lines for transmitting a plurality of data signals, each data line being disposed between columns of the plurality of pixel electrodes; a plurality of active elements for electrically connecting each of the plurality of pixel electrodes to its adjacent source bus line and thereby feeding the plurality of data signals to the plurality of pixel electrodes; and a plurality of gate bus lines for transmitting scanning signals for controlling the plurality of active elements so as to be in a conductive or non-conductive state, each gate bus line being disposed between rows of the plurality of pixel electrodes. The plurality of transmitted data signals are each held by parasitic capacitances of the plurality of source bus lines. The counter electrode has a plurality of apertures, and at least one of the plurality of apertures is disposed in a region opposed to the plurality of source bus lines.
