Abstract: The semiconductor device includes a substrate, first and second active patterns extending in a first direction, the second active pattern spaced apart from the first active pattern in a second direction different from the first direction, a gate electrode extending in the second direction, a first and second source/drain region each on one side of the gate electrode, a first and second source/drain contact each extending in the second direction on and connected to the first and second source/drain region respectively, and a contact separation layer separating the first and second source/drain contacts, the contact separation layer including a first portion and a second portion on first portion both between the first and second source/drain regions, wherein a width of the first portion of the contact separation layer in the first direction is greater than a width of the second portion of the contact separation layer in the first direction.

Abstract: A display device includes a substrate, a first display element which is disposed on the substrate, and a plurality of diffraction patterns which are disposed on a path of light emitted from the first display element and arranged along a direction with a first period. when a width of a cross section of one of the plurality of diffraction patterns is defined as a first length, the first period and the first length satisfy Inequality (1): 0.4 ? d ? 1 / DP ? 1 ? 1 , ( 1 ) where DP1 is the first period, and d1 is the first length.

Abstract: A driving apparatus for a liquid crystal display, which includes a first pixel, a second pixel and a third pixel that display different colors, includes: an image signal compensation unit that compensates input image signals corresponding to the first pixel, the second pixel, and the third pixel to generate compensated input image signals; and a data driver that supplies data voltages to the first pixel, the second pixel and the third pixel based on the compensated input image signals. The image signal compensation unit shifts a value of the input image signal corresponding to the first pixel by a first value with respect to a common voltage, shifts a value of the input image signal corresponding to the second pixel by a second value with respect to the common voltage, and shifts a value of the input image signal corresponding to the third pixel by a third value with respect to the common voltage.
