Abstract
A reflection type liquid crystal display device, having a first substrate having an array of a plurality of light reflecting pixel electrodes, a second substrate having an array of a plurality of microlenses, and liquid crystals sandwiched between the first and second substrates for modulating incident light entering between the first and second substrates and reflected by the pixel electrodes to form an optical display, wherein each of the light reflecting pixel electrodes includes a high reflectivity region formed near at a focal point upon which light incident upon a microlens is focussed, the high reflectivity region reflecting the incident light, and a low reflectivity region formed surrounding the high reflectivity region, the low reflectivity region limiting a reflection of incident light components of stray light to be caused by aberration among light passed through the microlens.
