Abstract
According to an aspect, a semi-transmissive liquid crystal display device includes a plurality of pixels arranged in a matrix, a plurality of reflective electrodes, a counter electrode facing the reflective electrode, and a liquid crystal layer. The reflective electrodes are provided for each of the pixels, and each of them includes a plurality of electrodes, with a combination of the areas of which area coverage modulation is performed by using n bits. The electrodes are configured such that a ratio of the sum of the perimeter(s) of electrode(s) corresponding to each bit of the n bits satisfies 1:2: . . . :2n-1. The liquid crystal layer is provided between the reflective electrode and the counter electrode. The semi-transmissive liquid crystal display device is configured to carry out reflective display using the reflective electrode and carry out transmissive display using at least a space of the reflective electrode between the pixels.
