Abstract: A semiconductor device includes: an active pattern extending in a first direction across an underlying substrate, a gate structure extending in a second direction, on the active pattern, a first source/drain contact electrically connected to a source/drain region within the active pattern, on one side of the gate structure, and a first via pattern electrically connected to an upper surface of the first source/drain contact. A rail pattern is provided, which extends in the first direction, and is spaced apart from the first via pattern in the second direction. A wiring pattern extends in the first direction, and is electrically connected to an upper surface of the rail pattern. The first source/drain contact includes a first recess therein, which is more recessed downwardly relative to the upper surface of the first source/drain contact, and at least a portion of the first recess extends adjacent to the rail pattern.

Abstract: A backlight unit is provided, which includes a light-emitting diode LED, an LED driving unit which drives the LED, a control unit which measures a temperature of the LED driving unit, and, if the temperature exceeds a preset threshold temperature, interrupts an operation of the LED driving unit, and a threshold temperature adjustment unit which changes the preset threshold temperature based on a limit temperature of a circuit element included in the LED driving unit.

Abstract: A liquid crystal display (LCD) apparatus is provided. The LCD apparatus includes a frame, a liquid crystal panel which is disposed inside the frame, at least one fluorescent lamp which is disposed inside the frame to project light toward the liquid crystal panel, a voltage supply printed circuit board (PCB) which supplies a driving voltage to the fluorescent lamp and includes a connection end and at least one connection terminal arranged on the connection end; and at least one fluorescent lamp connector to which the fluorescent lamp and the voltage supply PCB are connected and which includes a PCB insertion recess into which the connection end is inserted, and the PCB insertion recess has opposite sides which are open in a width direction of the fluorescent lamp connector.
