Disclosed is a conventional organic light emitting diode (OLED) having one reflective electrode in combination with at least one transparent OLED in stacked configuration functioning as backlighting in a transflective display apparatus such as a liquid crystal display (LCD). Preferably, at least two transparent OLEDs are arranged in a stacked configuration with one conventional OLED, each of the three OLEDs emitting light of a different bandwidth. The reflective electrode located behind the backlight also serves as a reflecting plate for the display. This arrangement enhances reflectivity and permits color sequencing in the transmissive mode, allowing all the components of a full color display (i.e. red, green, blue) to emit through the same pixel without the need for a color filter.

The present invention has cement as basic material; light aggregate to replace partial or even all broken stone and river sand for reduced dead weight; fiber, polymer and expanding ingredient to form interpenetrating network structure resulting in raised wear resisting, crack resisting and penetration resisting performance; and black coloring agent to match the color of the other bridge parts.

A passivation layer is formed by coating a flowable insulating material on the substrate where a thin film transistor and a storage capacitor electrode, and a pixel electrode is formed on the passivation layer. A portion of the passivation layer is etched using the pixel electrode as a mask to make a groove on the thin film transistor, and then a black matrix is formed by filling an organic black photoresist in the groove. To increase the storage capacitance, a portion of the passivation layer is removed or to form a metal pattern on the storage capacitor electrode. A flowable insulating material is used as a gate insulating layer to planarize the substrate. In the case of the etch stopper type thin film transistor, a photo definable material is used as the etch stopper layer to reduce the parasitic capacitance between the gate electrode and the drain electrode.

The invention relates to a reflection-type TFT (Thin Film Transistor) LCD (liquid crystal display) and a making method thereof. A light absorption layer is arranged below a reflection surface, rays can enter the light absorption layer below the reflection surface through a light absorption gap and can be absorbed by the light absorption layer without irradiating the upper surface of a driving part to cause the failure of the driving part. Accordingly, the light absorption layer can substitute a black light-shielding layer in the prior art, and a black border region is formed between two adjacent pixels. The pixel electrodes or the reflection layer is extremely thin, and the pattern making thereof has extremely high accuracy so that the pattern of the black border region also has extremely high accuracy. Moreover, the black border region and the pixel electrodes are formed on the same substrate, the problem of pattern pasting contraposition errors among different substrates is inessential, and contraposition errors of different film layers of the same substrate are generally very small so that the black border region can be designed very narrow to acquire a larger pixel reflection display area and an effective reflection area ratio.

In a black light unit, a light-guide plate is provided with a cone pattern to uniformly guide a light beam passing through a light input. A light-path converter controls a progress direction of the light beam in such a manner that the light beam outputted from the light-guide plate is progressed in a direction perpendicular to a liquid crystal panel. A diffusion sheet diffuses the light beam passing through the light-path converter into the liquid crystal panel. A reflection of the light-guide pattern and wall surface and the bright lines of the light input can be minimized. The light efficiency can be improved and the manufacturing cost can be reduced.
