A liquid crystal display device having a first sub pixel and a second sub pixel. The first sub pixel corresponds to a first color layer having a first color. The second sub pixel, corresponds to a second color layer having a second color. The first and second sub pixels each have a rectangular shape that includes a pair of longer sides. A first reflective region and a second reflective region, in which first and second reflective films are disposed, each extend across the first sub pixel and the second sub pixel respectively between the longer sides. A first transmissive region and a second transmissive region, in which the reflective films are not disposed, each extend entirely across the first sub pixel and the second sub pixel respectively between the longer sides, An area of the first reflective region is different from an area of the second reflective region.

In an IC mounting regionof a substrateconstituting a liquid crystal device, first terminalsA,B, andC are divided into a plurality of terminalsA,A,A,A,B,B,C, andC by slitsformed of portions where an ITO film forming wiring patternsand the first terminalsis not formed. For this reason, when the first terminalsand first electrodesare electrically and mechanically connected by an anisotropic conductive film, a resin component contained in the anisotropic conductive film fixedly bonds a driving ICto the second transparent substratewhile it enters the slits. Since the area of the resin componentof the anisotropic conductive film in contact with the first terminalsis large, fixing strength of the ICis increased.

A transflective liquid crystal display device comprising a pair of substrates; a liquid crystal layer between the substrates; reflective films are provided on an internal surface of a lower substrate which reflects light incident from an upper substrate; color filters provided above the reflective films, each containing a plurality of color layers which have different colors and are disposed to correspond to dots forming a display region; and lighting means. The dots have a reflective region in which the reflective film is present and a transmissive region in which the reflective film is not present. In addition, the color filters have opening portions that overlap the reflective film in each dot. Since the non-color regions are provided in the color filter corresponding to the reflective films, light used in reflective display mode is sufficiently secured and the chroma in a transmissive display mode can be maintained.

Liquid crystal display device, substrate assembly for liquid crystal display device, and electronic apparatus having a substantially equivalent display quality in both transmissive and reflective display modes

In a liquid crystal panelprovided with first and second substratesandbonded by a sealant, alignment layersandfor covering electrodesA andA, respectively, are formed up to the regions overlapping the regions for forming up to. Accordingly, since there is no space between the alignmentorand the sealant, a low twist domain does not occur in a liquid crystal. Therefore, the vicinity of the inner periphery of the sealant can also be effectively used as the region for displaying images.

In an electro-optic device, connection to first electrodesof a first transparent substrateextending in one direction from the side, to which signals are inputted, is established through electrical conduction between two substrates in a width-wise central area of the first transparent substrate using first terminals. To second electrodesof a second transparent substratewhich are routed toward the outer side, signals are directly inputted from second terminals. The obliquely routed second electrodesare formed of, e.g., an aluminum alloy film, and slit-like openings are formed in the second electrodesto allow passage of light emitted from a backlight device
