摘要： Source lines cross, over an intervening first insulation film, gate lines on an insulation substrate. Switching elements are on crossings between the gate lines and the source lines. Pixel electrodes are connected to the switching elements. Common electrodes facing the pixel electrodes generate between the pixel electrodes and the common electrodes an electric field directed approximately parallel to the insulation substrate. First shielding electrode patterns along the source lines in a layer, with the first insulation film intervening, underneath the source lines, at least partially overlap the source lines widthwise. Plural second shielding electrode patterns are formed along the source lines, overlapping the first shielding electrode patterns and without substantially overlapping the source lines in a layer, with a second insulation film intervening, above the source lines. The first shielding electrode patterns having a same electric potential as the plural second shielding electrode patterns.

摘要： A semi-transparent TFT array substrate has a TFT including a source electrode, a gate electrode, and a drain electrode. The substrate also has an auxiliary capacitive wiring and a reflective pixel electrode. Further, the substrate has a transparent pixel electrode including an electrode extending from a corner of the rest of the transparent pixel electrode to an edge of the auxiliary capacitive wiring closest to a gate wiring connected to the gate electrode. In addition, the substrate has a source wiring connected to the source electrode. The auxiliary capacitive wiring overlaps a space existing between the reflective pixel electrode and the source wiring. The electrode is disposed between the reflective pixel electrode and the source wiring. A connection which connects the electrode and the rest of the transparent pixel electrode does not overlap the auxiliary capacitive wiring in a plan view. The connection does not overlap the gate wiring.
