摘要： Power consumption required for charging and discharging a source signal line is reduced in an active matrix EL display device. A bipolar transistor (Bi1) has a base terminal B connected to an output terminal c1 of an operational amplifier (OP1), a collector terminal C connected to a low power potential (GND), and an emitter terminal E connected to a resistor R2. A high power potential (VBH) is a potential in synchronization with a high power potential of a light emitting element. A potential of the output terminal c1 of the operational amplifier (OP1) is outputted as a buffer low power potential (VBL). The low power potential (VBL) corresponds to a potential difference between the high power potential (VBH) and a high power potential (V1). Accordingly, the low power potential (VBL) can follow the high power potential (VBH), that is a high power potential of the light emitting element.

摘要： A display device which operates appropriately independently of the manufacture variations of each element formed over a substrate is provided without increasing the number of components. The display device includes an external correction circuit and a panel, and the external correction circuit and the panel are connected to each other through a flexible printed wiring connecting portion. The panel includes a signal line driver circuit, a scan line driver circuit, a pixel portion, a monitoring element portion, a D/A converter and a constant current source. When mounting the D/A converter on a substrate, the number of external circuit components can be reduced without increasing flexible printed wiring terminals by supplying a digital signal inputted to the D/A converter from a video signal line, and controlling the sampling timing of the digital signal with a signal used in the panel.

摘要： A manufacturing method of a display device, which prevents electrostatic breakdown of the display device both before and after a circuit test without reducing the productivity in forming a plurality of display devices on a substrate to be processed by a step-and-repeat exposing method. A wiring pattern group led out from signal input terminals of the display devices to the edge of the substrate to be processed is efficiently formed by exposing to light through a repetitive pattern integrated with a display device pattern. Depending on the states of the wiring pattern group as to contact or non-contact with a detachable and conductive component, the signal input terminals of the display devices can be easily switched between in a short circuited state and a non-short circuited state. Accordingly, both the measure against electrostatic breakdown and the circuit test are achieved in the display devices on the substrate to be processed.

摘要： A driving method is provided which improves the duty ratio, which presents high image quality by securing a sufficient length of sustain (lighting) period when gray scales are increased in number, and which prolongs the lifetime of a light emitting element. One frame period has m (m is a natural number equal to or larger than 2) different sub-frame periods SF1, SF2, . . . , and SFm. The m different sub-frame periods SF1, SF2, . . . , and SFm each have an address period and a sustain period. Analog data signals are inputted to their respective light emitting elements in the address period. In the sustain period, the light emitting elements emit light in response to the analog data signals at n (n is a natural number equal to or larger than 2) levels of luminance for gray scale display.
