[0017] Please refer to figure 1 , which shows a schematic diagram of a color filter substrate (ColorFilter Substrate) 100 according to the first embodiment of the present invention. The color filter substrate 100 includes a light shielding layer 110 and a filter material layer 120 . The light-shielding layer 110 (also called a black matrix) has a light-transmitting opening 111 (the area shown by the dotted line). The filter material layer 120 covers at least the light-transmitting opening 111 . In this embodiment, the filter material layer 120 completely covers the light-transmitting opening 111 and a part of the light-shielding layer 110 . The filter material layer 120 has a trapezoidal protruding portion 121 corresponding to a first light-transmitting long side 111 a of the light-transmitting opening 111 and covering part of the light-shielding layer 110 . Such as figure 1 As shown, the filter material layer 120 is not a straight line at the first light-transmitting long ...

[0038] Please refer to Figure 4 , which shows a schematic diagram of the color filter substrate 300 according to the second embodiment of the present invention. The difference between the color filter substrate 300 of this embodiment and the color filter substrate 100 of the first embodiment is that the filter material layer 320 of this embodiment has two trapezoidal protrusions, and the rest of the same parts are no longer restate.

[0039] Such as Figure 4 As shown, the filter material layer 320 has a first trapezoidal protruding portion 321 and a second trapezoidal protruding portion 322, and the first trapezoidal protruding portion 321 and the second trapezoidal protruding portion 322 correspond to the first trapezoidal protruding portion 322 of the light transmission opening 111 respectively. The light-transmitting long side 111a and the second light-transmitting long side 111b. The first trapezoidal protrusions 321 and the second trapezoidal protrusions 322 are arra...

[0046] Please refer to Image 6 , which shows a schematic diagram of a color filter substrate 500 according to a third embodiment of the present invention. The difference between the color filter substrate 500 of this embodiment and the color filter substrate 100 of the first embodiment is that the filter material layer 520 of this embodiment has three trapezoidal protrusions, and the rest of the same parts are no longer restate.

[0047] Such as Image 6 As shown, the filter material layer 520 has a first trapezoidal protrusion 521 , a second trapezoidal protrusion 522 and a third trapezoidal protrusion 523 . The first trapezoidal protrusions 521 , the second trapezoidal protrusions 522 and the third trapezoidal protrusions 523 are arranged in a staggered manner. The first trapezoidal protrusion 521 corresponds to the midpoint of the first light-transmitting long side 111a of the light-transmitting opening 111, and the second trapezoidal protrusion 522 and the third trapez...

Abstract

The invention discloses a colorful filter-sheet substrate and a patterning mask. The colorful filter-sheet substrate comprises a shading layer and a filter material layer; wherein, the shading layer is provided with a penetrating opening, and the filter material layer at least covers the penetrating opening. The filter material layer is provided with a trapezoidal raised part, a long penetrating edge of which is corresponding to the penetrating opening and covers a part of the shading layer.

Description

【Technical field】 [0001] The invention relates to a color filter substrate and a patterned mask, and in particular to a color filter substrate and a patterned mask that can reduce mask fogging. 【Background technique】 [0002] The liquid crystal display panel has the advantages of small size, high image quality and long lifespan, so that the liquid crystal display panel is widely used in various electronic devices. The liquid crystal display panel is mainly composed of a backlight module, a thin film transistor substrate and a color filter substrate. In the process of manufacturing thin film transistor substrates and color filter substrates, the photolithography process is a common process step. [0003] As for the color filter, in the photolithography process of patterning the filter material layer, a mask is used as a shield, and a light beam is used to expose a filter material layer. [0004] However, during the exposure process of the filter material layer, the light be...
