Abstract:
1. A liquid crystal display apparatus comprising: a first substrate on an incident side comprising a first polarizing plate; a second substrate, opposite to the first substrate with respect to the incident side, comprising a second polarizing plate, an absorbing axis of the first polarizing plate being substantially perpendicular to that of the second polarizing plate; a liquid crystal layer between the first and second substrates including liquid crystal molecules aligned in a direction in parallel to the substrates and rotated within a plane in parallel to the first substrate when electric fields are applied to the liquid crystal molecules in a direction in parallel to the first substrate; a group of electrodes comprising pairs of electrodes defining pixels on a near side to the liquid crystal layer of either of the first or second substrate for generating the electric fields to provide active matrix driving; and an illumination unit, wherein each of the first and second polarizing plates comprises supporting plates at both sides thereof, the first and second polarizing plates comprise first and second optical phase compensation films for compensating polarizing conditions of transmitted polarizing light on sides of the liquid crystal layer, respectively; slow axes of the first and second optical retardation compensation films are substantially in parallel to absorbing axes of the first and second polarizing plates, respectively, a smaller angle between the slow axis and the absorbing axis ranges from 0 to 2 degrees, and a thickness dr
