Patent ID: 6933998

Claim:
A display device, comprising: a semiconductor substrate; an array of control elements including drive lines formed on the semiconductor substrate; and an array of reflective pixel electrodes arranged in rows and columns, the array of pixel electrodes being stacked over the array of control elements so that each of the control elements controls a state of reflection of a corresponding one of the pixel electrodes, wherein: each of the reflective pixel electrodes has a substantially rectangular shape having a first aspect ratio, and the control elements are formed in respective second substantially rectangular regions defined by a crossing matrix of lines parallel to the drive lines and, closely arranged side-by-side, each of the second regions having a second aspect ratio different from the first aspect ratio; and the control elements are arranged (i) in a first direction that makes an angle greater than zero and smaller than 90° with a direction of the rows of the reflective pixel electrodes, and (ii) in a second direction perpendicular to the first direction.
