Abstract

A liquid crystal display apparatus includes a liquid crystal display unit, a plurality of data driving units which provide image data to said liquid crystal display unit, and a control unit which enables said plurality of data driving units to take in the image data simultaneously if the image data to be provided to said data driving units are identical.

Claims (4)

1. A method of making a liquid crystal display apparatus that displays an image on a liquid crystal panel including liquid crystal cells, comprising a step of determining a γ value serving as an index for a graduation-luminosity characteristic according to a thickness of the liquid crystal cell or a birefringence index of a liquid crystal layer included in the liquid crystal cells.

2. A liquid crystal display apparatus that displays an image on a liquid crystal panel including liquid crystal cells, wherein a γ value which serves as an index of gradation-luminosity characteristic in said liquid crystal panel is set to above 1.9 and within a ±30% range of 0.008 times Δnd where Δn represents an anisotropy of a refractive index and d represents a thickness of said liquid crystal cells.

3. The liquid crystal display apparatus as claimed in claim 2 , wherein said γ value is set between 2.15 and 3 while the product Δnd is within limits of 350 nm±50 nm.

4. The liquid crystal display apparatus as claimed in claim 2 , wherein said γ value is set between 2.0 and 2.3 while the product Δnd is within limits of 280 nm±50 nm.
