PURPOSE:To realize the reflection type electrooptic device which eliminates the need for a light shield mask by installing an insulating reflection body on the liquid crystal side of a switching element array substrate provided with a switching element array between two substrates where liquid crystal is sandwiched. CONSTITUTION:A liquid crystal layer 104 is sandwiched between the two opposite substrates 102 and 103 and the insulating reflection body 101 is provided on the switching element array substrate 103 on the side of the liquid crystal layer 104. This liquid crystal layer 104 is a twisted nematic liquid crystal layer which converts linear polarized incident light into nearly elliptic polarized light by its reflecting surface and rotates the plane of polarization of the incident light after the reflection by 90 deg. into linear polarized light on its projection surface. When no electric field is applied, a nontransmission state (black) is entered, so the peripheral part of each picture element is shielded automatically from light and the switching element array is shielded from light almost completely, so the need for a light shield mask is eliminated and mask positioning is therefore unnecessary. |
