A retardation film which is manufacturable by a simple process, and being capable of preventing a decline in light use efficiency is provided. A retardation film includes: a substrate having a plurality of grooves extending in a specific direction on a surface thereof; and a retardation layer arranged in contact with the surface of the substrate, and including a liquid crystal material, the liquid crystal material being aligned along the extending direction of the plurality of grooves and being polymerized.

Retardation film, method of manufacturing the same, and display

A thin type image display device for displaying an image by emitting light from a fluorescer with irradiation of electron beams thereto. The device has a cathode panel between a front panel and a back panel in such a manner that a space is existent between the cathode panel and the back panel, wherein through holes for diffusion of getters are formed in the cathode panel to maintain the image quality at the center of a display screen, or the cathode panel is supported by getters to maintain a required pressure, hence attaining a higher image quality even on a large-sized display screen. A gate electrode may be composed of a getter material.
