Method of designing position of micro-lens for optical panel device, method of producing optical panel device, and optical panel device

Abstract

A minimum frame is set to cover the shape of an opening of each pixel of an optical panel portion, and an intersection between two diagonals of the frame is determined. An X-axis and a Y-axis are set with the intersection between the diagonals taken as a reference point. A ratio between areas, occupied on both sides of the X-axis, of the opening is calculated and a correction amount in the Y-axis direction is calculated on the basis of the area ratio. Similarly, a ratio of areas, occupied on both sides of the Y-axis, of the opening is calculated and a correction amount in the X-axis direction on the basis of the area ratio. The intersection is moved by the correction amounts in the X-axis direction and the Y-axis direction, to obtain plane coordinates. The center position of a micro-lens is aligned to the plane coordinates corresponding to the center of gravity of the opening of the pixel. In this way, the position of a micro-lens is suitably set to the opening of each pixel of the optical panel portion on the basis of the opening shape of the pixel.
