Abstract:
1. A liquid crystal display device comprising a display panel including a plurality of pixel regions arranged in matrix on a substrate, a plurality of transistors formed for each pixel region, a plurality of gate lines for connecting gate electrodes of the plurality of transistors, a plurality of data signal lines for connecting first electrodes of the plurality of transistors, a storage capacitor wherein one electrode is connected to a second electrode of said transistor, a storage capacitor line for connecting the other electrode of said storage capacitor, and a liquid crystal layer arranged between one electrode of said pixel region connected to the second electrode of said transistor and the other electrode opposing to the electrode, wherein: said storage capacitor is connected to a gate line of the former stage and has the Cs-on-gate structure wherein a storage capacitor is superimposed on the gate line; a reflection portion and transmission portion are arranged in each of said pixel regions; and a reflectance of light by the reflection portion of a selected pixel is 1% or more and 30% or less of the light incident thereon for defining an entire display signal range from a lowest value to highest value, and a transmittance of light by the transmission portion of a selected pixel is at most 4% or more and 10% or less of the light incident thereon for defining an entire display signal range from a lowest value to highest value; wherein the liquid crystal display device includes a polarization plate and further wherein a polarity of a counter potential is inverted for every horizontal scanning period, the display having a resolution of at least 200 ppi, and further wherein the reflection portion extends perpendicularly above a CS formation region, and the reflection portion of each pixel is substantially centrally located over at least one conductive member located at a single outer side edge of the transmission portion and extending substantially along an entire length of the outer side edge of the transmission portion such that each of a plurality of adjacent pixels have corresponding reflective portions with common boundary regions, wherein light amount of the display light is 20 cd/m
