A liquid crystal display includes a liquid crystal display panel having a pixel array including a first group of liquid crystal cells connected to odd-numbered gate lines and a second group of liquid crystal cells connected to even-numbered gate lines and a data driving circuit including a latch array. Each liquid crystal cell of the second group shares a data line with one liquid crystal cell of the first group adjacent to the liquid crystal cell of the second group in an extension direction of the gate lines. The latch array delays only second group data to be applied to the liquid crystal cells of the second group among digital video data for one horizontal line by about one half horizontal period in response to a data rendering control signal.

A nonaqueous electrolyte for a lithium secondary battery and a lithium secondary battery including the same are provided. In particular, the nonaqueous electrolyte comprises a compound of chemical formula 1 as an electrolyte additive: NC—(R1)n-A-(R2)m—CN 1 wherein, R1 and R2 represent, respectively, alkylene groups, n and m represent integers of 1 to 10, and A is an aromatic hydrocarbon in which the number of carbons is 5 to 9 or O. When the lithium secondary battery is kept at high voltage and temperature, the electrolyte additive reduces gas generation, thereby reducing battery swelling. Therefore, it is possible to reduce a battery thickness increment rate and to increase discharge capacity at a high temperature.
