The present invention is directed to the provision of a display apparatus that can achieve an improvement in display quality by adjusting the wiring resistance ratio of wiring lines. The display apparatus () according to the present invention comprises a first substrate (), a second substrate (), and a seal member (), wherein first driving electrodes (-to-) are electrically connected at first transfer-connection positions (Tto T) to first wiring lines (-to-) via the seal member, and second driving electrodes are electrically connected at second transfer-connection positions (Tto T) to second wiring lines (-) via the seal member, the first transfer-connection positions are provided at positions respectively offset in a first direction from the extended lines of the respective first driving electrodes, and the second transfer-connection positions are provided at positions respectively offset from the extended lines of the respective second driving electrodes in a second direction which is different from the first direction.

Display device having first and second offsetting transfer-connections connected between driving electrodes and wiring lines and bent respectively in different directions to adjust wiring line resistances

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.
