Abstract:
1. A display apparatus, comprising: a plurality of pixels disposed m an array, each pixel including an electro-optical element, a write transistor configured to write a picture signal, a drive transistor configured to drive the electro-optical element according to the picture signal written by the write transistor, and a hold capacitor, connected between the gate and source electrodes of the drive transistor, and configured to hold the picture signal written by the write transistors; wherein the plurality of pixels are all grouped into pairs, each pair comprising pixels adjacent to one another in the row direction, each of said pairs has an auxiliary capacitor area that straddles a boundary between the pixels of the respective pair, respective layouts of the auxiliary capacitor areas being substantially the same as one another, each pixel of a first subset of the plurality of pixels includes an auxiliary capacitor comprising a first electrode connected to the anode of the electro-optical element of the respective pixel and a second electrode connected to a first potential node, a region of overlap of the first and second electrodes defining the auxiliary capacitor, where a layout of the auxiliary capacitor corresponds to the auxiliary capacitor area of the pair that includes the respective pixels, and each of the pairs that does not include a pixel of the first subset has an island metal pattern, which is not the auxiliary capacitor of any of the plurality of pixels, and whose layout corresponds to the auxiliary capacitor area of the respective pair.
