Abstract: A data driver includes a first latch, a second latch, a digital-to-analog converter, and an output buffer. The first latch sequentially stores first line data in response to a first sampling signal and outputs the stored data in parallel. The second latch sequentially stores second line data in response to a second sampling signal and outputs the stored data in parallel. The digital-to-analog converter converts the parallel data provided from one of the first and second latches to data voltages. The output buffer outputs the data voltages in response to a delay clock.

Abstract: A display device includes a display panel and a light source configured to provide a first color light to the display panel. The display panel includes a first display substrate (DS), a second DS facing the first DS, a column spacer disposed between the first and second DSs, and a liquid crystal layer filled between the first and second DSs. The first DS includes: a first base substrate (FBS); a thin film transistor (TFT) disposed on the FBS, the TFT including a gate electrode, first and second electrodes, and an activation layer; a first insulation layer (IL) covering the TFT and disposed on the FBS; and a second IL disposed on the first IL and including an opening exposing a first portion of the first IL overlapping the activation layer. The column spacer is disposed on the first portion to cover the activation layer and shield the first color light.
