Description of the Invention: [Technical Field] The present invention relates to a display device, and more particularly to a transflective LCD and a method of fabricating the same. [Prior Art] Liquid crystal display (LCD) devices have been widely used in electronic devices such as portable computers, personal digital assistants (PDAs), and mobile phones. LCD devices can be classified into two types: "transmissive" and "reflective". The transmissive LCD device uses backlight as the light source, while the reflective LCD device uses ambient light as the light source. Because the transmissive LCD device uses a backlight, the transmissive lCD garment can have a brighter display and can be used in environments with insufficient ambient light. However, this backlight makes the transmissive LCD device more power consuming and makes the device bulky. Conversely, since the reflective gas LCD is placed in ambient light, it has the advantage of being more power efficient. However, the reflective [[o device is not easy to display images in an environment with insufficient ambient light. In order to overcome the shortcomings of the above two types of LCD devices, a transflective LCD device has been developed. The transflective LCD device can display images in the penetrating and reflective modes. Under strong ambient light, the backlight of the transflective LCD device can be turned off, thus reducing the monthly b! consumption. When the ambient light is insufficient, the backlight of the semi-transparent sLCD| can be turned on, thereby changing the display quality of the conventional reflective LCD device. 1 and FIG. 1 is an exploded perspective view of a conventional transflective LCD device. The known half-transparent LCD device includes mutually opposing - the upper substrate 1 () and the lower substrate 2 (), and the liquid crystal layer % sandwiched between the upper and lower substrates. The upper wire (10) is often referred to as a color filter plate (4) 〇r filtersubstrate) lG ' and the lower substrate is as commonly referred to as a lining substrate (& ah_her). • On the surface of the upper substrate 1 of the lower substrate 20, a black matrix (1 matrix) l2 w and a color filter 14 including red (8), green (9) and blue _) are formed, wherein black is in a matrix type. And surround each color light film 14. More on the upper substrate 1 ,, formed

The transparent portion 22a comprises • a transparent conductor material such as indium tin oxide (IT〇) or indium zinc oxide (IZ〇). The opaque portion _ 22b contains a highly reflective metal material such as A1. Please refer to Fig. 2, which is a cross-sectional view showing the operation mode of the conventional transflective LCD device. A conventional transflective LCD device includes a lower substrate 200, an upper substrate 260, and a liquid crystal layer 230 sandwiched between the upper and lower substrates. The lower substrate 200 has an insulating layer 2 and a halogen electrode formed thereon.

The backlight element 290 generally includes a plurality of fluorescent tubes arranged in parallel on a light guide plate, and has a reflective plate for enhancing brightness and a diffusion layer for uniformly illuminating the LCD on the light guide plate. For example, in a portable display device, a cold cathode fluorescent tube having a small diameter can be mounted on one end of the light guide plate or face up, thereby enabling light to be directed to the 丄CD panel. The upper substrate 260 has a common electrode 24A and a color filter 25A formed thereon, and the color filter 250 includes three main color regions of r, G, and b. On the outer side of the upper substrate 26, an upper compensation film 293 and an upper polarizer 294 can be formed.

0773-A30903TWF 6 J275864 如上述，液晶層230是夾於下基板200與上基板260之間。半穿透式 LCD裝置因而能夠在穿透模式與反射模式下操作。例如在穿透模式下操作時，從背光元件290來的背光280可穿透透明部分224以及通過彩色濾光片250而環；t兄光270可被不透明部分222反射，然後再次通過彩色濾光片 250。然而，由於習知的半穿透式LCD裝置仍然需要裝設於lCD面板下方 .的#光元件，因此增加裝频積、厚度與重量，並增加了製造成本。除此 . 之外，在習知的半穿透式裝置中，偏光片是被裝設於lcd面板的外 • 側，因此偏光片與LCD面板之間可能會有間隙(_，這會導致漏光而降低 LCD裝置的光效率。【發明内容】有鑑於此’本發明之一目的，在於提供一種半穿透式lcd裝置及造方法。 /' 為達上述目的，本發明提供一種半穿透式LCD裝置，包括：一第一兵板與^二基板；-液晶層，夾於第_基板與第二基板之間；—發光元件二位於第基板的-邊上；包含有複數個凹口的—絕緣層，形成於第一基板門呈^中Γ自凹吨含1—侧壁與—第二侧壁，第二側壁與水平方向之 Ζΐ Γ反射層，形成於絕緣層上，並延伸至第二側壁上， /、弟-側壁上的第-反射層是面向發光,· 於第-反射制上方。丨偏光片形成本發明亦提供-種半穿透式LCD的製造 — I —第-美杯·报#勹人> / ·k七、一弟一基板一凹口包含一第〜、、、巴、味層於弟一基板上，其中每角；形成一液晶層而夾於第一其* 门之間/、有一夾 -基板的-邊上·《、ί 弟二基板之間；配置-發光元件於第成—弟—反射層於絕緣層上，並延伸至第二側壁上，0773-A30903TWF 6 J275864 As described above, the liquid crystal layer 230 is sandwiched between the lower substrate 200 and the upper substrate 260.

The insulating layer 320 may also be formed to cover the first substrate 310. As shown, the insulating layer 320 includes a plurality of notches 322. Each of the notches 322 includes a --side wall 3221 and a - first side wall 3222. In some embodiments, the bottom width of the recess 322 is narrower than the top width of the recess 322.
