Patent ID: 7460116

Claim:
A display device comprising: an image display portion comprising an arrangement of a plurality of display elements, each of the display elements comprising an electro-optical element that is driven by a current, a control element for controlling the current flowing through the electro-optical element, a selection element for applying to the control element a data signal for controlling the control element, a scanning signal line electrode for applying to the selection element a scanning signal for controlling the selection element, a data signal line electrode for applying to the selection element the data signal, and a power source line electrode for applying to the control element the current for driving the electro-optical element; and a current supply portion for applying a current from a current supply point to a series of power supply line electrodes made by connecting the power supply line electrodes of the plurality of display elements in series; wherein a maximum rate indicating the current variation per one centimeter calculated based on a first current flowing through a first electro-optical element comprised by a first display element which is furthest away from the current supply point and a second current flowing through a second electro-optical element comprised by a second display element different from the first display element is 2%/cm or less when the first and the second electro-optical elements are driven.
