Abstract: A display device includes: an array substrate; a counter substrate; a liquid crystal layer between the array substrate and the counter substrate; and a light source disposed so as to emit light into a side surface of the array substrate or a side surface of the counter substrate. The array substrate includes: signal lines arranged in a first direction with spaces interposed between the signal lines; scan lines arranged in a second direction with spaces interposed therebetween; a switching element coupled to a corresponding one of the scan lines and a corresponding one of the signal lines; an organic insulating layer that covers at least the switching element; and a metal layer provided on the upper side of the organic insulating layer so as to overlap the organic insulating layer. A positional misalignment portion of each signal line does not overlap a positional misalignment portion of the metal layer.

Abstract: A data driver for a matrix display device includes a shift register circuit for sequentially shifting a sampling start pulse in response to a clock signal to produce a plurality of sampling signals. A plurality of sample/hold circuits sample display data in response to a sampling signal supplied thereto. The driver also includes a switching circuit which transfers each of the sampling signals to an associated one of the sample/hold circuits in a sequential-sampling mode and the selected signals to the sample/hold circuits such that one of the selected sampling signals is supplied in common to at least two of the sample/hold circuits.
