摘要： A display apparatus employs a pixel array section including pixel circuits forming a matrix, signal lines as columns, scan lines as rows and power-supply lines, and driving sections. The driving sections are a signal selector, a write scanner and a drive scanner. The signal selector provides an electric potential representing a gradation or a predetermined reference electric potential. The write scanner provides a control signal. The drive scanner provides a power-supply voltage changing the electric potential from high to low. The drive scanner drives adjacent power-supply lines as a group. The number of lines as a group is determined in advance. The drive scanner switches a power-supply voltage from high to low and vice versa, and applies the voltage to groups by shifting the phase from group to group. The voltage is supplied to a group at the same phase and switched the electric potential.

摘要： A pixel has an outer region extending linearly along a boundary with an adjacent pixel and an inner region extending along the inner side of the outer region. Wiring lines are arranged across the outer region and the inner region. An outer uneven zone is formed along the outer region and on a substrate due to level differences resulting from the presence of the wiring lines. Similarly, an inner uneven zone is formed along the inner region and on the substrate due to level differences resulting from the presence of the wiring lines. A pattern of a conductor film of which the wiring lines are made is formed properly such that recessed portions of the outer uneven zone are located directly behind their corresponding raised portions of the inner uneven zone, as viewed from inside the pixel.
