Abstract

The invention relates to a display structure comprising an electrode layer () superposed on a sub-layer () wherein a surface of the sub-layer facing the electrode layer is roughened. In particular, the display structure may relate to a TFT stack comprising a layer of an electrode metal corresponding to a pixel electrode (). The pixel pad together with the data line () is used for charging of the pixel pad. The gate electrode () used is separated from the source and drain electrode () by a dielectric layer (). The structural layers of the TFT may be deposited on a suitable flexible substrate (). In order to prevent defects in the light modulating layer () from being visible, a surface of the sub-layer () underlying the electrode layer () is roughened. It is desirable to provide such improvement to, among others, electrophoretic-type displays and liquid crystal-type displays.
