Abstract
A liquid crystal display apparatus integrated with a tablet for preventing the undesired color development due to double refraction of light passing the STN liquid crystal display cell from occurring also in high-temperature environment. An STN liquid crystal display cell and a tablet are arranged between a pair of polarizing plates. A compensating liquid crystal layer for canceling the wavelength scattering due to double refraction of light passing the liquid crystal display cell is arranged between opposing coordinates detecting electrodes of this tablet. In addition, nonconductive spacer particles and conductive particles are mixed in the compensating liquid crystal layer.
