COLOR SLIPPAGE INSPECTING METHOD FOR COLOR FILTER-LESS LIQUID CRYSTAL PANEL

摘要

PROBLEM TO BE SOLVED: To provide a color slippage inspecting method for color filter-less liquid crystal panel capable of evaluating the color slippage by an inspection system simpler than heretofore. ;SOLUTION: The color slippage by a microlens 3 of a color filter-less liquid crystal panel, in which a blue pixel 4B, a red pixel 4R and a green pixel 4G are regularly arranged on the light exit side corresponding to blue light, red light and green light, which has a microlens 3 for introducing the indent light beams of blue light B, red light R and green light G, adjusted in advance so as to be made incident at a prescribed angle on the light entrance side, to the corresponding color pixels, and which has a control means for controlling the transmission of the incident beams introduced by the microlens 3 through the respective color pixels, is inspected. The incident light is restricted only to a kind or two kinds from among blue light, red light and green light, the control means controls so that the color pixel corresponding to the light having the restricted color does not transmit the light through and the color pixel corresponding to the light having the non-restricted color transmit the light through.;COPYRIGHT: (C)1998,JPO
