Embodiment Construction

[0044] The organic electroluminescent display and its manufacturing method of the present invention will now be described in detail with reference to the accompanying drawings, and preferred embodiments will be listed as follows.

[0045] Please refer to figure 2 , which is a cross-sectional view of the organic electroluminescence display of the present invention. Each pixel structure of the organic electroluminescent display 20 includes a thin film transistor 22 and an organic light emitting diode 24 disposed on a substrate 26 . There is an anti-reflection layer 28 and a light-shielding layer 29 between the TFT 22 and the substrate 26 , but there is no light-shielding layer 29 between the OLED 24 and the substrate 26 . The anti-reflection layer 28 is directly formed on the surface of the substrate 26 , and the light-shielding layer 29 covers the anti-reflection layer 28 and has an opening 292 to expose part of the anti-reflection layer 28 . The OLED 24 is located above the...

Abstract

There is disclosed a organic electroluminescent display, which includes a base plate, an antireflective layer, a shading layer, a thin film transistor and an organic light-emitting diode. Its manufacture method comprises the following steps: first, form the antireflective layer on the base plate; next, form the shading layer on the antireflective layer and define the shading layer as first and second zones; then, remove the shading layer in the first zone to expose the antireflective layer and at last make the thin film transistor above the shading layer in the second zone and form the organic light-emitting diode above the antireflective layer in the first zone.

Description

technical field [0001] The invention relates to an organic electroluminescent display and a manufacturing method thereof, in particular to an organic electroluminescent display with an anti-reflection layer and a manufacturing method thereof. Background technique [0002] Contrast Ratio (CR) is one of the important pointers for consumers to choose and buy monitors. It is defined as the ratio of the brightness of the brightest point to the darkest point on the screen. A high contrast ratio means relatively high brightness and vivid colors. Based on this, manufacturers deduce that higher contrast ratio means better display quality. Because in this case, blacks will be darker and whites will be "whiter", so that the display can display more colors. [0003] An organic electroluminescent display panel is a self-luminous display that has a minimum brightness when it is not emitting light. According to the above definition of contrast ratio, if the contrast ratio of the organic...
