Abstract
A liquid crystal display device capable of canceling out effects of signal charges, even when a columnar spacer bears signal charges, and preventing disturbance in a transverse electric field, includes pairs of columnar spacers that are disposed in two unit pixels adjacent to each other in a row direction or in a column direction. Each pair of columnar spacers is spaced from all other pairs of columnar spacers by at least two pixels of a row or a column.
