Abstract
An active matrix liquid crystal display device has diamond-shaped pixels arrayed in a close-packed arrangement, and interconnected by row and column electrodes which zigzag between the pixels, each column electrode extending between and being common to two columns of pixels and their associated thin film switches, and the column electrode-switch connections alternating sequentially between pixel columns.
