Plane display element
View Patent ↗An electric field shielding wiring is provided in the gap between the pixel electrodes adjacent in parallel to the signal line, to minimize the inter-electrode parasitic capacity generated in the gap between the pixel electrodes, which is caused by the change in the pixel potential of the pixel electrode when the polarity of the signal line potential is changed, and prevent an increase in the pixel potential of the pixel electrode of the previous stage.
1. A plane display element comprising a first substrate including a plurality of switching elements arranged in the proximity of an intersection of signal line and scanning line placed crossing each other on a base material, pixel electrodes arranged like a matrix along said signal line and scanning line and connected to said signal line via said switching element, an auxiliary capacity line made in one body with said scanning line and having via a dielectric layer said pixel electrode to create auxiliary capacity, a second substrate includes a plurality of opposite electrode arranged opposite to said first substrate with a certain gap taken therebetween, and an optical modulation layer sealed in the gap between said first substrate and said second substrate;
wherein the potential polarity of said pixel electrode arranged along said signal line is different for every two pixels, and an electric field shield wiring is further provided between said pixel electrode of the previous stage line connected to said scanning line of the previous stage and said pixel electrode of the next line connected to said scanning line of the next stage;
wherein said scanning line includes said auxiliary capacity line and said electric field shielding wiring made in one body through a slit, and one end of said pixel electrode is disposed within a slit area of said scanning line.
