Abstract
In a liquid crystal display device including a liquid crystal display panel () including a liquid crystal layer () sandwiched between a first substrate () and a second substrate () having transparent electrodes () on inner surfaces opposing to each other, the film thickness of at least one of the transparent electrodes () formed on the first and second substrates () is set so that light passing through the transparent electrode and exhibiting a maximum transmittance has a color within either a region defined by an x value of 0.22 to 0.28 and a y value of 0.21 to 0.31 or a region defined by an x value of 0.28 to 0.34 and a y value of 0.22 to 0.35 in a chromaticity diagram of a CIE 1931 color system using a white light source. This reduces coloring irregularities due to a film thickness error caused during manufacturing of the transparent electrodes to enable performance of uniform display.
