Display device and electronic machine

Abstract

The patent relates to a display device and a electric device. A bank layer 221 and a recessed compartment area 223 compartmentalized by the bank layer 221 are arranged in a predetermined matrix pattern on the substrate 20. A real pixel part 111 for display and a dummy pixel part 112 not for display are formed in a pixel part to be a display part. A scanning line driving circuit 80 for controlling the output of scanning signals that pass through scanning lines and a drive controlling signal conducting part 320 through which drive control signals pass to drive the scanning line driving circuit 80 are also provided on the substrate 20. In the plan view of the substrate 20, the drive controlling signal conducting part 320 is superimposed at least partly on the recessed compartment area 223 of the dummy pixel part 112. Thereby, the display and electronic instrument can effectively utilize a substrate surface, and prevent or suppress a external effect on a drive controlling signal.

Description

technical field [0001] The present invention relates to a display device and its electronic equipment. Background technique [0002] Conventionally, optical display devices such as liquid crystal display devices and EL display devices have a structure in which a plurality of circuit elements, electrodes, liquid crystal or EL elements, etc. are stacked on a substrate. For example, in an EL display device, a light-emitting layer including a light-emitting substance is sandwiched between an anode and a cathode electrode layer, and the holes injected from the anode side and the electrons injected from the cathode side are used to create a fluorescent energy. A phenomenon in which light is emitted when the light-emitting layer is recombined and loses momentum from the excited state. [0003] As a driving method of such an EL display device, it is known that scanning lines in the row direction and data lines in the column direction are arranged in a matrix, and at the same time, ...

AI Technical Summary

Problems solved by technology

In such a display device, there is a problem that the drive circuit and / or control circuit must be arranged on the substrate, which increases the size of the substrate, or the area where these circuits are arranged is difficult to use as a display area, so it cannot be used. Effective use of the substrate as a display area

In addition, not only the connection wires from the designated power supply to the above-mentioned drive circuit and / or control circuit must also be arranged on the substrate, but also the connection wires from the control circuit to the drive circuit must also be arranged on the substrate, thus further reducing the display area. utilization efficiency
