Abstract: Disclosed is a reflection type liquid crystal display (LCD) and a manufacturing method thereof. A first substrate on which a pixel array is formed is prepared. A second substrate is formed facing the first substrate. A liquid crystal layer is formed between the first and second substrates. A reflective electrode is formed on the first substrate. The reflective electrode includes a plurality of first regions and a plurality of second regions having a height difference relative to the first regions, in which a first total sum in length components of the second regions arranged along a direction perpendicular to a first direction is greater than a second total sum in length components of the second regions arranged along a direction perpendicular to a second direction such that the second regions have higher reflectivity in the first direction relative to the second direction. A reflective electrode of oriented micro lenses defined by the first grooves and the second grooves is provided to enhance a reflection efficiency. The contrast and image quality are improved remarkably. The micro lenses are suitable for electronic displays that need a high reflectivity towards a specific direction. Since the reflective electrodes may be formed by an improved exposure and development process, the manufacturing cost and time would be reduced.
