A display device can include a substrate including an active area including a plurality of sub-pixels and a non-active area, a plurality of light-emitting elements disposed in the plurality of sub-pixels, a plurality of data lines disposed in the active area, a plurality of data link lines disposed in the active area and configured to transmit a data voltage to the plurality of data lines, driving transistors disposed in the plurality of sub-pixels, and a shielding layer disposed on the driving transistors to overlap a conductive layer connected to a source electrode of one of the driving transistors. A constant voltage can be applied to the shielding layer and thus, the occurrence of screen spots can be reduced in the display device.

Display device

A plasma processing apparatus comprising a processing chamber, a dielectric, an antenna, and a first to third electromagnet groups is disclosed. In the processing chamber, a mounting table having a mounting surface is included and a plasma process is performed. A surface of the dielectric faces the mounting surface. The antenna, provided on the opposite surface of the dielectric, introduces an electric field into the processing table through the dielectric to form plasma. The first electromagnet group, provided at a position higher than the mounting surface on an outer perimeter of the processing chamber, forms a first magnetic field above the mounting surface. The second electromagnet group, provided inside the mounting table along an outer perimeter thereof, and the third electromagnet group, provided at a position corresponding to the second electromagnet group on the outer perimeter of the processing chamber, cooperate with each other to form a second magnetic field around the mounting surface.

Plasma processing apparatus

A plasma processing apparatus includes a plasma processing chamber, a substrate support disposed in the plasma processing chamber, an annular baffle plate disposed so as to surround the substrate support, the annular baffle plate having a plurality of openings, a first annular plate disposed below the annular baffle plate, a second annular plate disposed below the first annular plate, the second annular plate having an annular overlapping portion vertically overlapping with a part of the first annular plate, a pressure detector configured to detect a pressure in the plasma processing chamber, and at least one actuator configured to vertically move at least one of the first and second annular plates so as to change a distance between the first annular plate and the second annular plate based on the detected pressure.

Plasma processing apparatus and plasma processing method

An electroluminescent display and a method of driving the same are disclosed. The electroluminescent display includes a display panel including a plurality of pixels electrically connected to a plurality of data lines and a plurality of gate lines. Each pixel includes a driving element adjusting a current of a light emitting element depending on a gate-to-source voltage, and a switching element supplying a second voltage to the driving element in response to a gate-on voltage of an emission control signal. The switching element is turned off in response to a gate-off voltage of the emission control signal during a real-time compensation time. A source voltage of the driving element is changed during the real-time compensation time.
