Optical film inside a liquid crystal display

An LCD comprising

• 1) a liquid crystal (LC) cell comprising the following elements, starting from the edges to the centre of the cell in the sequence listed below
• a) a first and a second substrate plane (11a, 11b) parallel to each other, at least one of which is transparent to incident light,
• b) optionally an array of nonlinear elements (12) on one of said substrates which can be used to individually switch individual pixels of said LC cell,
• c) a color filter array (13) provided on one of said substrates, said color filter optionally being covered by a planarization layer (14),
• d) a first electrode layer (15a or 15b) provided on the inside of said first substrate,
• e) optionally a second electrode layer (15a or 15b) provided on the inside of said second substrate,
• f) optionally first and second alignment layers (16a or 16b) provided on said first and second electrodes,
• g) an LC medium (17) that is switchable between at least two different states by application of an electric field,
• 2) a first linear polarizer on one side of the LC cell,
• 3) optionally a second linear polarizer on the side of the LC cell opposite to that of the first linear polarizer,
• 4) at least one optical retardation film (18),
• wherein at least one of said optical retardation films is positioned between the first and second substrate (11a, 11b) of the LC cell, between the color filter and the LC medium.
