Abstract
Official abstract text for this publication.
A liquid crystal display device comprising: a liquid crystal cell including a quadrilateral display surface and a liquid crystal layer enclosed between glass substrates and controlling light entering from a second surface side and exiting to a first surface side; a first polarizing plate including a polarizer having an absorption axis and adhered to the first surface side with an adhesive layer; and a second polarizing plate including a polarizer having an absorption axis and adhered to the second surface side with an adhesive layer such that one of the polarizing plates including the polarizer with a larger maximum dimension in an absorption axis direction on the display surface is adhered to the glass substrate with an adhesive layer having higher adhesion strength to the glass substrate than the adhesive layer of other polarizing plates including the polarizer with a smaller maximum dimension in the absorption axis direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid crystal display device comprising: a liquid crystal cell including a liquid crystal layer enclosed between glass substrates, the liquid crystal cell having a first surface and a second surface opposite to the first surface, the first surface being quadrilateral, the liquid crystal cell controlling light entering from the second surface to make the light to transmit through the liquid crystal cell and to exit from the first surface; a first polariz…
