According to one embodiment, a display device includes a first substrate provided with electrodes and wiring lines, a second substrate provided with wiring lines and opposing the first substrate, and a connector which connects the wiring lines on the first substrate and the wiring lines on the second substrate. The connector includes a support member formed of a resin and a plurality of wiring portions on the support member, and each wiring portion includes a first junction joined to the wiring lines of the first substrate, a second junction joined to the wiring lines of the second substrate, a coupling section located between the first junction and the second junction and embedded inside of the support member.

Display device

A display device comprises a plurality of first to fourth switching elements. On the basis of control signals from the drive control circuit, the common line is brought to the selected state when the common line is connected to the low-voltage portion for common lines by turning on the first switching element and turning off the second switching element; the common line is brought to the non-selected state when the common line is brought to the high-impedance state by turning off both the first and second switching elements; the data line is brought to the selected state when the data line is connected to the high-voltage portion for data lines by turning off the third switching element and turning on the fourth switching element; and the data line is brought to the non-selected state when the data line is connected to the low-voltage portion for data lines by turning on the third switching element and turning off the fourth switching element.

Matrix display device, matrix display driving method, and matrix display driver circuit

A drive circuit for driving a display device includes a voltage level shift circuit which receives a control signal and a data signal and which shifts a voltage level of the control signal and the data signal to output a voltage level shifted control signal and a voltage level shifted data signal. The drive circuit also includes an output circuit which receives the voltage level shifted data signal and which outputs an output data signal corresponding to the voltage level shifted data signal in response to the voltage level shifted control signal.

Drive circuit and display unit for driving a display device and portable equipment
